67b922bac1 Avoid GraphQL schema rebuild when changing irrelevant Metadata
This increases the speed of `create_query_collection` and `add_collection_to_allowlist` by a factor ~~10~~ 65, by caching the in-memory GraphQL schema. This speedup also applies more broadly to Metadata changes relating to:
- allowlists
- query collections
- cron triggers
- REST endpoints
- API limits
- metrics config
- GraphQL introspection options
- TLS allow lists
- OpenTelemetry

When is construction of the in-memory GraphQL schema cached between Metadata operations?

Before this PR, **never**! It's rebuilt fully, for every role, on every Metadata operation.

However, there are many Metadata operations that don't influence the GraphQL schema. So we should be caching its construction.

The `Hasura.Incremental` framework allows us to cache such constructions: whenever we have an arrow `Rule m a b`, where `a` is the input to the arrow and `b` the output, we can use the `Inc.cache` combinator to obtain a new arrow which is only re-executed when the input `a` changes in a material way. To test this, `a` needs an `Eq` instance. (Before hasura/graphql-engine-mono#6877, this was a `Cacheable` type class which has now been removed.)

We can't simply apply `Inc.cache` to the "Steps 3 and 4" in `buildSchemaCacheRule`, because the inputs (components of `BuildOutputs` such as `SourceCache`) don't have an `Eq` instance.

So the changes to `buildSchemaCacheRule` restructure the code so that the input to "Step 1", namely the Metadata, can be used as a caching key instead, so that `Inc.cache` can be applied to the whole sequence of steps.

That works to cache construction of the GraphQL schema, but it means that now only those Metadata operations that _don't_ influence any of the products of steps 1-4 can use a cached build of the GraphQL schema. The most important intermediate product is `BuildOutputs`. So now the exercise becomes to minimize the amount of stuff stored in `BuildOutputs`, so that as many Metadata operations as possible can be handled outside of the codepath that produces a GraphQL schema.

Per hasura/graphql-engine-mono#6609, the `BuildOutputs` structure is too big, and stores things unnecessarily. Refer to the PR description there for reasoning - the same logic applies to this PR, and simply goes a few steps further. In doing so, it can benefit from hasura/graphql-engine-mono#6765, which allows us to verify at compile time that certain Schema Cache building steps _don't_ generate "Metadata dependencies". If a certain Metadata dependency is never generated, we don't need to handle that case in `deleteMetadataObject`. Thus such intermediate products don't need to be passed through `resolveDependencies`, and thus they don't need to be stored in `BuildOutputs`, and thus their rebuild won't trigger a GraphQL schema rebuild.

6ac67a5566 Allow collecting metadata dependencies and inconsistencies separately
`CollectedInfo` was just an awkward sum type. By using an explicit `Either` instead, we can guarantee at the type level that certain methods only write inconsistencies, or only write dependencies. This is useful, because if we can guarantee that no dependencies are written, then we don't need to run `resolveDependencies` on that part of the Metadata. In other words, we can keep it out of `BuildOutputs`, which greatly benefits performance - see e.g. hasura/graphql-engine-mono#6613.

2d055df2a4 server: Simplify BuildOutputs
A bunch of configurations are retrieved from the Metadata, then stored in the `BuildOutputs` structure, only to then be forwarded to the `SchemaCache`, with extremely little processing in between.

So this simplifies the build pipeline for some parts of the metadata: just construct those things from `Metadata` directly, and store them in the `SchemaCache` without any intermediate container.

Why did we have the detour via `BuildOutputs` in the first place? Parts of the Metadata (codified by `MetadataObjId`) can generate _metadata inconsistencies_ and/or _schema dependencies_, which are related.

- Metadata inconsistencies are warnings that we show to the user, indicating that there's something wrong with their configuration, and they have to fix it.
- Schema dependencies are an internal mechanism that allow us to build a consistent view of the world. For instance, if we have a relationship from DB tables `books` to `authors`, but the `authors` table is inconsistent (e.g. it doesn't exist in the DB), then we have schema dependencies indicating that. The job of `resolveDependencies` is to then drop the relationship, so that we can at least generate a legal GraphQL schema for `books`.

If we never generate a schema dependency for a certain fragment of Metadata, then there is no reason to call `resolveDependencies` on it, and so there is no reason to store it in `BuildOutputs`.

---

The starting point that allows this refactor is to apply Metadata defaults before it reaches `buildAndCollectInfo`, so that metadata-with-defaults can be used elsewhere.

342391f39d Upgrade Ormolu to v0.5.
This upgrades the version of Ormolu required by the HGE repository to v0.5.0.1, and reformats all code accordingly.

Ormolu v0.5 reformats code that uses infix operators. This is mostly useful, adding newlines and indentation to make it clear which operators are applied first, but in some cases, it's unpleasant. To make this easier on the eyes, I had to do the following:

* Add a few fixity declarations (search for `infix`)
* Add parentheses to make precedence clear, allowing Ormolu to keep everything on one line
* Rename `relevantEq` to `(==~)` in #6651 and set it to `infix 4`
* Add a few _.ormolu_ files (thanks to @hallettj for helping me get started), mostly for Autodocodec operators that don't have explicit fixity declarations

In general, I think these changes are quite reasonable. They mostly affect indentation.

a01d1188f2 scaffolding for remote-schemas module
The main aim of the PR is:

1. To set up a module structure for 'remote-schemas' package.
2. Move parts by the remote schema codebase into the new module structure to validate it.

## Notes to the reviewer

Why a PR with large-ish diff?

1. We've been making progress on the MM project but we don't yet know long it is going to take us to get to the first milestone. To understand this better, we need to figure out the unknowns as soon as possible. Hence I've taken a stab at the first two items in the [end-state](https://gist.github.com/0x777/ca2bdc4284d21c3eec153b51dea255c9) document to figure out the unknowns. Unsurprisingly, there are a bunch of issues that we haven't discussed earlier. These are documented in the 'open questions' section.

1. The diff is large but that is only code moved around and I've added a section that documents how things are moved. In addition, there are fair number of PR comments to help with the review process.

## Changes in the PR

### Module structure

Sets up the module structure as follows:

```
Hasura/
  RemoteSchema/
    Metadata/
      Types.hs
    SchemaCache/
      Types.hs
      Permission.hs
      RemoteRelationship.hs
      Build.hs
    MetadataAPI/
      Types.hs
      Execute.hs
```

### 1. Types representing metadata are moved

Types that capture metadata information (currently scattered across several RQL modules) are moved into `Hasura.RemoteSchema.Metadata.Types`.

- This new module only depends on very 'core' modules such as
  `Hasura.Session` for the notion of roles and `Hasura.Incremental` for `Cacheable` typeclass.

- The requirement on database modules is avoided by generalizing the remote schemas metadata to accept an arbitrary 'r' for a remote relationship
  definition.

### 2. SchemaCache related types and build logic have been moved

Types that represent remote schemas information in SchemaCache are moved into `Hasura.RemoteSchema.SchemaCache.Types`.

Similar to `H.RS.Metadata.Types`, this module depends on 'core' modules except for `Hasura.GraphQL.Parser.Variable`. It has something to do with remote relationships but I haven't spent time looking into it. The validation of 'remote relationships to remote schema' is also something that needs to be looked at.

Rips out the logic that builds remote schema's SchemaCache information from the monolithic `buildSchemaCacheRule` and moves it into `Hasura.RemoteSchema.SchemaCache.Build`. Further, the `.SchemaCache.Permission` and `.SchemaCache.RemoteRelationship` have been created from existing modules that capture schema cache building logic for those two components.

This was a fair amount of work. On main, currently remote schema's SchemaCache information is built in two phases - in the first phase, 'permissions' and 'remote relationships' are ignored and in the second phase they are filled in.

While remote relationships can only be resolved after partially resolving sources and other remote schemas, the same isn't true for permissions. Further, most of the work that is done to resolve remote relationships can be moved to the first phase so that the second phase can be a very simple traversal.

This is the approach that was taken - resolve permissions and as much as remote relationships information in the first phase.

### 3. Metadata APIs related types and build logic have been moved

The types that represent remote schema related metadata APIs and the execution logic have been moved to `Hasura.RemoteSchema.MetadataAPI.Types` and `.Execute` modules respectively.

## Open questions:

1. `Hasura.RemoteSchema.Metadata.Types` is so called because I was hoping that all of the metadata related APIs of remote schema can be brought in at `Hasura.RemoteSchema.Metadata.API`. However, as metadata APIs depended on functions from `SchemaCache` module (see [1](ceba6d6226/server/src-lib/Hasura/RQL/DDL/RemoteSchema.hs (L55)) and [2](ceba6d6226/server/src-lib/Hasura/RQL/DDL/RemoteSchema.hs (L91)), it made more sense to create a separate top-level module for `MetadataAPI`s.

   Maybe we can just have `Hasura.RemoteSchema.Metadata` and get rid of the extra nesting or have `Hasura.RemoteSchema.Metadata.{Core,Permission,RemoteRelationship}` if we want to break them down further.

1. `buildRemoteSchemas` in `H.RS.SchemaCache.Build` has the following type:

   ```haskell
   buildRemoteSchemas ::
     ( ArrowChoice arr,
       Inc.ArrowDistribute arr,
       ArrowWriter (Seq CollectedInfo) arr,
       Inc.ArrowCache m arr,
       MonadIO m,
       HasHttpManagerM m,
       Inc.Cacheable remoteRelationshipDefinition,
       ToJSON remoteRelationshipDefinition,
       MonadError QErr m
     ) =>
     Env.Environment ->
     ( (Inc.Dependency (HashMap RemoteSchemaName Inc.InvalidationKey), OrderedRoles),
       [RemoteSchemaMetadataG remoteRelationshipDefinition]
     )
       `arr` HashMap RemoteSchemaName (PartiallyResolvedRemoteSchemaCtxG remoteRelationshipDefinition, MetadataObject)
   ```

   Note the dependence on `CollectedInfo` which is defined as

   ```haskell
   data CollectedInfo
     = CIInconsistency InconsistentMetadata
     | CIDependency
         MetadataObject
         -- ^ for error reporting on missing dependencies
         SchemaObjId
         SchemaDependency
     deriving (Eq)
   ```

   this pretty much means that remote schemas is dependent on types from databases, actions, ....

   How do we fix this? Maybe introduce a typeclass such as `ArrowCollectRemoteSchemaDependencies` which is defined in `Hasura.RemoteSchema` and then implemented in graphql-engine?

1. The dependency on `buildSchemaCacheFor` in `.MetadataAPI.Execute` which has the following signature:

   ```haskell
   buildSchemaCacheFor ::
     (QErrM m, CacheRWM m, MetadataM m) =>
     MetadataObjId ->
     MetadataModifier ->
   ```

   This can be easily resolved if we restrict what the metadata APIs are allowed to do. Currently, they operate in an unfettered access to modify SchemaCache (the `CacheRWM` constraint):

   ```haskell
   runAddRemoteSchema ::
     ( QErrM m,
       CacheRWM m,
       MonadIO m,
       HasHttpManagerM m,
       MetadataM m,
       Tracing.MonadTrace m
     ) =>
     Env.Environment ->
     AddRemoteSchemaQuery ->
     m EncJSON
   ```

   This should instead be changed to restrict remote schema APIs to only modify remote schema metadata (but has access to the remote schemas part of the schema cache), this dependency is completely removed.

   ```haskell
   runAddRemoteSchema ::
     ( QErrM m,
       MonadIO m,
       HasHttpManagerM m,
       MonadReader RemoteSchemasSchemaCache m,
       MonadState RemoteSchemaMetadata m,
       Tracing.MonadTrace m
     ) =>
     Env.Environment ->
     AddRemoteSchemaQuery ->
     m RemoteSchemeMetadataObjId
   ```

   The idea is that the core graphql-engine would call these functions and then call
   `buildSchemaCacheFor`.

e3c2bf53a5 Move, document, and prune action types and custom types types.
### Description

This PR is a first step in a series of cleanups of action relationships. This first step does not contain any behavioral change, and it simply reorganizes / prunes / rearranges / documents the code. Mainly:
- it divides some files in RQL.Types between metadata types, schema cache types, execution types;
- it renames some types for consistency;
- it minimizes exports and prunes unnecessary types;
- it moves some types in places where they make more sense;
- it replaces uses of `DMap BackendTag` with `BackendMap`.

Most of the "movement" within files re-organizes declarations in a "top-down" fashion, by moving all TH splices to the end of the file, which avoids order or declarations mattering.

### Optional list types

One main type change this PR makes is a replacement of variant list types in `CustomTypes.hs`; we had `Maybe [a]`, or sometimes `Maybe (NonEmpty a)`. This PR harmonizes all of them to `[a]`, as most of the code would use them as such, by doing `fromMaybe []` or `maybe [] toList`.

74513e351f Use an enum for EndpointMethod and fix incorrect response aggregation.
### Description

This small PR improves the representation of an endpoint method from `Text` to an enum of the supported methods. Additionally, it cleans some of the instances defined on surrounding types (such as Postgres-specific instances on Endpoint types).

Due to a name conflict, this makes `RQL.Types.Endpoint` impossible to re-export from `RQL.Types`, which in turn forces several other modules to import it explicitly, which I think is fine since we want to ultimately get rid of `RQL.Types`.

aaadd2c81f Build schema cache for relationships from remote schemas
## Description

This PR is a subset of #3069, that does roughly that #3031 was aiming to do: add the schema cache building phase for relationships from remote servers. This PR does not change any of the code that *uses* remote relationships, meaning we ignore the added schema cache information. It also contains dependency-tracking code, which was originally missing from #3031; in turn, this pulls some of the metadata API as well, since we identify remote relationships by how they were created.

8e88e73a52 server/mssql: add cascade to mssql_run_sql
<!-- Thank you for ss in the Title above ^ -->

## Description
<!-- Please fill thier. -->
<!-- Describe the changes from a user's perspective -->
We don't have dependency reporting mechanism for `mssql_run_sql` API i.e when a database object (table, column etc.) is dropped through the API we should raise an exception if any dependencies (relationships, permissions etc.) with the database object exists in the metadata.

This PR addresses the above mentioned problem by
-> Integrating transaction to the API to rollback the SQL query execution if dependencies exists and exception is thrown
-> Accepting `cascade` optional field in the API payload to drop the dependencies, if any
-> Accepting `check_metadata_consistency` optional field to bypass (if value set to `false`) the dependency check

### Related Issues
<!-- Please make surt title -->
<!-- Add the issue number below (e.g. #234) -->
Close #1853

### Solution and Design
<!-- How is this iss -->
<!-- It's better if we elaborate -->
The design/solution follows the `run_sql` API implementation for Postgres backend.

### Steps to test and verify
<!-- If this is a fehis is a bug-fix, how do we verify the fix? -->
- Create author - article tables and track them
- Defined object and array relationships
- Try to drop the article table without cascade or cascade set to `false`
- The server should raise the relationship dependency exists exception

da8f6981d4 server: reduce the number of backend dispatches
Fixes https://github.com/hasura/graphql-engine-mono/issues/712

Main point of interest: the `Hasura.SQL.Backend` module.

This PR creates an `Exists` type indexed by indexed type and packed constraint while hiding all of its complexity by not exporting the constructor.

Existential constructors/types which are no longer (directly) existential:
- [X] BackendSourceInfo :: BackendSourceInfo
- [x] BackendSourceMetadata :: BackendSourceMetadata
- [x] MOSourceObjId :: MetadatObjId
- [x] SOSourceObj :: SchemaObjId
- [x] RFDB :: RootField
- [x] LQP :: LiveQueryPlan
- [x] ExecutionStep :: ExecStepDB

This PR also removes ALL usages of `Typeable.cast` from our codebase. We still need to derive `Typeable` in a few places in order to be able to derive `Data` in one place. I have not dug deeper to see why this is needed.

92026b769f [Preview] Inherited roles for postgres read queries
fixes #3868

docker image - `hasura/graphql-engine:inherited-roles-preview-48b73a2de`

Note:

To be able to use the inherited roles feature, the graphql-engine should be started with the env variable `HASURA_GRAPHQL_EXPERIMENTAL_FEATURES` set to `inherited_roles`.

Introduction
------------

This PR implements the idea of multiple roles as presented in this [paper](https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/FGALanguageICDE07.pdf). The multiple roles feature in this PR can be used via inherited roles. An inherited role is a role which can be created by combining multiple singular roles. For example, if there are two roles `author` and `editor` configured in the graphql-engine, then we can create a inherited role with the name of `combined_author_editor` role which will combine the select permissions of the `author` and `editor` roles and then make GraphQL queries using the `combined_author_editor`.

How are select permissions of different roles are combined?
------------------------------------------------------------

A select permission includes 5 things:

1. Columns accessible to the role
2. Row selection filter
3. Limit
4. Allow aggregation
5. Scalar computed fields accessible to the role

 Suppose there are two roles, `role1` gives access to the `address` column with row filter `P1` and `role2` gives access to both the `address` and the `phone` column with row filter `P2` and we create a new role `combined_roles` which combines `role1` and `role2`.

Let's say the following GraphQL query is queried with the `combined_roles` role.

```graphql
query {
   employees {
     address
     phone
   }
}
```

This will translate to the following SQL query:

```sql

 select
    (case when (P1 or P2) then address else null end) as address,
    (case when P2 then phone else null end) as phone
 from employee
 where (P1 or P2)
```

The other parameters of the select permission will be combined in the following manner:

1. Limit - Minimum of the limits will be the limit of the inherited role
2. Allow aggregations - If any of the role allows aggregation, then the inherited role will allow aggregation
3. Scalar computed fields - same as table column fields, as in the above example

APIs for inherited roles:
----------------------

1. `add_inherited_role`

`add_inherited_role` is the [metadata API](https://hasura.io/docs/1.0/graphql/core/api-reference/index.html#schema-metadata-api) to create a new inherited role. It accepts two arguments

`role_name`: the name of the inherited role to be added (String)
`role_set`: list of roles that need to be combined (Array of Strings)

Example:

```json
{
  "type": "add_inherited_role",
  "args": {
      "role_name":"combined_user",
      "role_set":[
          "user",
          "user1"
      ]
  }
}
```

After adding the inherited role, the inherited role can be used like single roles like earlier

Note:

An inherited role can only be created with non-inherited/singular roles.

2. `drop_inherited_role`

The `drop_inherited_role` API accepts the name of the inherited role and drops it from the metadata. It accepts a single argument:

`role_name`: name of the inherited role to be dropped

Example:

```json

{
  "type": "drop_inherited_role",
  "args": {
      "role_name":"combined_user"
  }
}
```

Metadata
---------

The derived roles metadata will be included under the `experimental_features` key while exporting the metadata.

```json
{
  "experimental_features": {
    "derived_roles": [
      {
        "role_name": "manager_is_employee_too",
        "role_set": [
          "employee",
          "manager"
        ]
      }
    ]
  }
}
```

Scope
------

Only postgres queries and subscriptions are supported in this PR.

Important points:
-----------------

1. All columns exposed to an inherited role will be marked as `nullable`, this is done so that cell value nullification can be done.

TODOs
-------

- [ ] Tests
   - [ ] Test a GraphQL query running with a inherited role without enabling inherited roles in experimental features
   - [] Tests for aggregate queries, limit, computed fields, functions, subscriptions (?)
   - [ ] Introspection test with a inherited role (nullability changes in a inherited role)
- [ ] Docs
- [ ] Changelog

4815fcd500 server: progress on generic metadata
This PR generalizes a bunch of metadata structures.

Most importantly, it changes `SourceCache` to hold existentially quantified values:
```
data BackendSourceInfo =
  forall b. Backend b => BackendSourceInfo (SourceInfo b)

type SourceCache = HashMap SourceName BackendSourceInfo
```

This changes a *lot* of things throughout the code. For now, all code using the schema cache explicitly casts sources to Postgres, meaning that if any non-Postgres `SourceInfo` makes it to the cache, it'll be ignored.

That means that after this PR is submitted, we can split work between two different aspects:
  - creating `SourceInfo` for other backends
  - handling those other sources down the line

* server: fix an introspection query caching issue (fix #4547) (#4661)

Introspection queries accept variables, but we need to make sure to
also touch the variables that we ignore, so that an introspection
query is marked not reusable if we are not able to build a correct
query plan for it.

A better solution here would be to deal with such unused variables
correctly, so that more introspection queries become reusable.

An even better solution would be to type-safely track *how* to reuse
which variables, rather than to split the reusage marking from the
planning.

* Don't compile in developer APIs by default

* Tighten up handling of admin secret, more docs

Store the admin secret only as a hash to prevent leaking the secret
inadvertently, and to prevent timing attacks on the secret.

NOTE: best practice for stored user passwords is a function with a
tunable cost like bcrypt, but our threat model is quite different (even
if we thought we could reasonably protect the secret from an attacker
who could read arbitrary regions of memory), and bcrypt is far too slow
(by design) to perform on each request. We'd have to rely on our
(technically savvy) users to choose high entropy passwords in any case.

* Lower stack chunk size in RTS to reduce thread STACK memory (closes #5190)

This reduces memory consumption for new idle subscriptions significantly
(see linked ticket).

The hypothesis is: we fork a lot of threads per websocket, and some of
these use slightly more than the initial 1K stack size, so the first
overflow balloons to 32K, when significantly less is required.

However: running with `+RTS -K1K -xc` did not seem to show evidence of
any overflows! So it's a mystery why this improves things.

GHC should probably also be doubling the stack buffer at each overflow
or doing something even smarter; the knobs we have aren't so helpful.

!!! WARNING !!!
Since all fields accept `null`, they all are technically optional in
the new schema. Meaning there's no such thing as a missing mandatory
field anymore: a field that doesn't have a default value, and which
therefore isn't labelled as "optional" in the schema, will be assumed
to be null if it's missing, meaning it isn't possible anymore to have
an error for a missing mandatory field. The only possible error is now
when a optional positional argument is omitted but is not the last
positional argument.

* [skip ci] cleanup of int scalar parser

* [skip ci] retro-compatibility of offset as string

* [skip ci] Remove commit from commit_diff.txt

Although strictly speaking we don't know if this will work correctly in PDV
if we would implement query plan caching, the fact is that in the theoretical
case that we would have the same issue in PDV, it would probably apply not just
to introspection, and the fix would be written completely differently.  So this
old commit is of no value to us other than the heads-up "make sure query plan
caching works correctly even in the presence of unused variables", which is
already part of the test suite.

* Add MonadTrace and MonadExecuteQuery abstractions (#5383)

Just like object types, interface types, and union types, we have to avoid
circularities when collecting input types from the GraphQL AST.

Additionally, this fixes equality checks for input object types (whose fields
are unordered, and hence should be compared as sets) and enum types (ditto).

These are functions on Types, not on Parsers.

* [skip ci] fix setup to fix backend only test

the order in which permission checks are performed on the branch is
slightly different than on master, resulting in a slightly different
error if there are no other mutations the user has access to. By
adding update permissions, we go back to the expected case.

In order to compile a profiling build, run:

$ cabal new-build -f profiling --enable-profiling

* [skip ci] Fix two warnings

We used to lookup the objects that implement a given interface by filtering all
objects in the schema document.  However, one of the tests expects us to
generate a warning if the provided `implements` field of an introspection query
specifies an object not implementing some interface.  So we use that field
instead.

* Delete code for "interfaces implementing ifaces" (draft GraphQL spec)

Previously I started writing some code that adds support for a future GraphQL
feature where interfaces may themselves be sub-types of other interfaces.
However, this code was incomplete, and partially incorrect.  So this commit
deletes support for that entirely.

* Ignore a remote schema test during the upgrade/downgrade test

The PDV refactor does a better job at exposing a minimal set of types through
introspection.  In particular, not every type that is present in a remote schema
is re-exposed by Hasura.  The test
test_schema_stitching.py::TestRemoteSchemaBasic::test_introspection assumed that
all types were re-exposed, which is not required for GraphQL compatibility, in
order to test some aspect of our support for remote schemas.

So while this particular test has been updated on PDV, the PDV branch now does
not pass the old test, which we argue to be incorrect.  Hence this test is
disabled while we await a release, after which we can re-enable it.

This also re-enables a test that was previously disabled for similar, though
unrelated, reasons.

* add haddock documentation to the action's field parsers

* Deslecting some tests in server-upgrade

Some tests with current build are failing on server upgrade
which it should not. The response is more accurate than
what it was.

Also the upgrade tests were not throwing errors when the test is
expected to return an error, but succeeds. The test framework is
patched to catch this case.

* [skip ci] Add a long Note about interfaces and object types

* Add bulldozer auto-merge and -update configuration

We still need to add the github app (as of time of opening this PR)

Afterwards devs should be able to allow bulldozer to automatically
"update" the branch, merging in parent when it changes, as well as
automatically merge when all checks pass.

This is opt-in by adding the `auto-update-auto-merge` label to the PR.

* Remove 'bulldozer' config, try 'kodiak' for auto-merge

see: https://github.com/chdsbd/kodiak

The main issue that bit us was not being able to auto update forked
branches, also:
https://github.com/palantir/bulldozer/issues/66
https://github.com/palantir/bulldozer/issues/145

* Cherry-picked all commits

* [skip ci] Slightly improve formatting

already done previously in a6450e126b, and
subsequently fixed for PDV in 70e89dc250

Co-authored-by: Auke Booij <auke@tulcod.com>

* Fix typo in Changelog.

* [skip ci] Update changelog.

* reuse type names to avoid duplication

* Fix Hashable instance for Definition

The presence of `Maybe Unique`, and an optional description, as part of
`Definition`s, means that `Definition`s that are considered `Eq`ual may get
different hashes.  This can happen, for instance, when one object is memoized
but another is not.
