Dupe of https://github.com/hasura/graphql-engine-mono/pull/2853 with branch renamed so it doesn't break a tool.

prev pr: https://github.com/hasura/graphql-engine-mono/pull/2911

next pr: https://github.com/hasura/graphql-engine-mono/pull/2922

This implements https://github.com/hasura/graphql-engine/issues/7801

Some points to keep in mind for review:

* How state is passed to the tests. Do we like how this works?
   * I quite like it, with the opaque type [`State`](68f33051ca/server/tests-hspec/Harness/State.hs (L17)), we can avoid churn when adding things.
   * The [setup/teardown](68f33051ca/server/tests-hspec/Spec.hs (L19-L31)) seems clean.
   * By using hspec's own means to pass and denote context, we avoid "getting new ideas" for how to structure the tests -- we use a standard. Hopefully, that means the tests' structure rarely change.
* The various flags passed in the [ServeOptions](68f33051ca/server/tests-hspec/Harness/Constants.hs (L123)) - if there are any causes for concern, raise them here. My thinking is that, there are lots. I've picked some "sane" defaults (mostly empty). The tests pass. I think as we add more complex tests, these flags will be scrutinised and updated as needed. I think it's valuable that all flags are explicitly listed here, though.

b167120f96 server: add explicit export lists in OSS server and enforce with warning
We'll see if this improves compile times at all, but I think it's worth
doing as at least the most minimal form of module documentation.

This was accomplished by first compiling everything with
-ddump-minimal-imports, and then a bunch of scripting (with help from
ormolu)

**EDIT** it doesn't seem to improve CI compile times but the noise floor is high as it looks like we're not caching library dependencies anymore

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

71af68e9e5 server: drop HasVersion implicit parameter (closes #2236)
The only real use was for the dubious multitenant option
--consoleAssetsVersion, which actually overrode not just
the assets version. I.e., as far as I can tell, if you pass
--consoleAssetsVersion to multitenant, that version will
also make it into e.g. HTTP client user agent headers as
the proper graphql-engine version.

I'm dropping that option, since it seems unused in production
and I don't want to go to the effort of fixing it, but am happy
to look into that if folks feels strongly that it should be
kept.

(Reason for attacking this is that I was looking into http
client things around blacklisting, and the versioning thing
is a bit painful around http client headers.)

47183e8a2c Add Execute part for the MySQL data loader
The Plan part is missing, because it needs support from FromIr. That'll come in a follow up commit.

**Next PR**: #2529

This is the result of splitting up the mega PR into more digestible chunks. This is the smallest subset I've been able to collect. Missing parts are noted in comments.

The code isn't reachable from Main, so it won't affect the test suite. It just gets compiled for now.

For context, this splits up work from https://github.com/hasura/graphql-engine-mono/pull/2332

fbd1262ea6 server: operation timeout with postgres cancelling
### Description

This PR implements operation timeouts, as specced in #1232.

RFC: [rfcs/operation-timeout-api-limits.md](c025a90fe9/rfcs/operation-timeout-api-limits.md)

There's still some things to be done (tests and docs most notably), but apart from that it can
be reviewed. I'd still appreciate feedback on the RFC!

TODO:
- [x] break out the `ApiLimits` refactoring into a separate PR: #2103
- [x] finish the `pg-client-hs` PR: https://github.com/hasura/pg-client-hs/pull/39
- [x] remove configurability, after testing, prior to merging
- [ ] tests: #2390 has some tests that I've run locally to confirm things work on a fundamental level
- [x] changelog
- [x] documentation
- [x] fill in the detailed PR checklist

### Changelog

- [x] `CHANGELOG.md` is updated with user-facing content relevant to this PR. If no changelog is required, then add the `no-changelog-required` label.

### Affected components

- [x] Server
- [ ] Console
- [ ] CLI
- [x] Docs
- [ ] Tests

### Related Issues

Product spec: #1232.

### Solution and Design

Compare `rfcs/operation-timeout-api-limits.md`.

### Steps to test and verify

Configure operation timeouts, e.g. by posting

```
{
  "type": "set_api_limits",
  "args": {
    "operation_timeout": {
      "global": 3
    }
  }
}
```

to `v1/metadata` to set an operation timeout of 3s. Then verify that
1. non-admin queries that take longer than 3s time out with a nice error message
2. that those queries return after ~3s (at least for postgres)
3. also that everything else still works as usual

### Limitations, known bugs & workarounds
- while this will cause slow queries against any backends to fail, it's only verified to actually interrupt queries against postgres
- this will only successfully short-cut (cancel) queries to postgres if the database server is responsive

#### Catalog upgrade
Does this PR change Hasura Catalog version?
- [x] No

#### Metadata

Does this PR add a new Metadata feature?
- [x] Yes
  - Does `run_sql` auto manages the new metadata through schema diffing?
    - [x] Not required
  - Does `run_sql` auto manages the definitions of metadata on renaming?
    - [x] Not required
  - Does `export_metadata`/`replace_metadata` supports the new metadata added?
    - [x] Yes

#### GraphQL
- [x] No new GraphQL schema is generated

#### Breaking changes

- [x] No Breaking changes

a206d04062 server, CI: use ormolu as a formatter for Haskell sources
### Description

- sets up a Makefile target for running ormolu to format and check source code
- updates CI to run ormolu instead of stylish-haskell (and to check instead of format actively)

Compare #1679.

Here's the plan for merging this:
1. merge this PR; at this point, all PRs will fail CI unless they have the `ignore-server-format-checks` label set
2. merge follow-up PR #2404 that does nothing but actually reformats the codebase
3. tag the merge commit as `post-ormolu` (also on `graphql-engine`, for the benefits of community contributors)
4. provide the following script to any devs in order to update their branches:
   ```
   $ git checkout my-feature-branch
   $ git merge post-ormolu^
   $ make format
   $ git commit -a -m "reformat with ormolu"
   $ git merge -s ours post-ormolu
   ```
   (I'll put this in the commit message)

bdacf1bd23 server: remove ApplicativeDo from default extensions
I spent half the day reducing a weird compile failure here https://github.com/hasura/graphql-engine-mono/pull/1593/files#r713102990 to this https://gitlab.haskell.org/ghc/ghc/-/issues/17768#note_378004. Seems ApplicativeDo makes a mess of non-applicative monadic do in some cases. Given our rather localized use of ApplicativeDo, seemed a good idea to remove it from the list of default extensions.

It appears that ApplicativeDo also buries some unused return value warnings, so this PR also silences those. We should check that none of those warnings were warranted though.

d900a65399 server: Reduce and localize CPP usage
Some of our use of CPP causes trouble for ormolu, compare https://github.com/tweag/ormolu/issues/774.
Specifically, for understandable reasons, it can't deal well with `#ifdef` use that is not at the top-level.

This PR removes the problematic usage in ways that I hope are also a net non-loss regardless of helping
out ormolu (or other tooling).

- The default value for enabled APIs moves to the top level, next to the command line help, so
  they'll stay in sync more easily.
- All the CPP around using `assertNFHere` is moved to one module.

07fd7324c3 server: enable StrictData by default (fix hasura/graphql-engine#3941)
## Description

Almost all our data structures use strictness annotations, following [our styleguide's principle](https://github.com/hasura/graphql-engine/blob/master/server/STYLE.md#dealing-with-laziness) of "by default, use strict data types and lazy functions". The very few cases where we actually need laziness were already explicitly labelled as lazy with the `~` prefix operator.

This PR simply globally enables `StrictData`, allowing us to express records without `!()` on every field, but makes no attempt at cleaning existing code.

904029aa7d Add fancier trace debugging functions to Hasura.Prelude
## Suggestion: Add fancier trace debugging functions to `Hasura.Prelude`

This PR adds two trace functions, `ltrace` and `ltraceM`, which use the `pretty-simple` package to `show` the input with nice formatting and colors for ease of reading (and comparing using diff tools such as `meld` or `vim-diff`).

I've also added warning pragmas to the functions, which means:
1. Traces will not be left in code, as CI builds with -Werror
2. Developers will have to change the `ghc-options` to `-Wwarn` in their `cabal.project.local` settings to use these functions

### Example

Usage:

```hs
selectFunctionAggregate ... = ... do
  ltraceM "functionInfo" function
  ...
```

Output to terminal looks like this:

### Dependencies

Requires adding the following dependencies:
  - prettyprinter-ansi-terminal-1.1.2 (BSD2)
  - pretty-simple-4.0.0.0 (BSD3)

Question: what is the process for adding new dependencies? How does decisions on this matter happen?

2c0a8d818c Kill Arbitrary, take 2 (fix #1736)
### Description

A first PR, #1947, removed all the `Arbitrary` stuff from our codebase. But #1740, merged on the same day, added some tests relying on `Arbitrary`. In the merge process, some unneeded `Arbitrary` code got reintroduced.

This PR removes all `Arbitrary` stuff from `src-lib`, and cleans / refactor `Hasura.Generator` in `src-test` to only reduce it to the bare minimum amount of `Arbitrary` instances.

7bead93827 server: remove remnants of query plan caching (fix #1795)
Query plan caching was introduced by - I believe - hasura/graphql-engine#1934 in order to reduce the query response latency. During the development of PDV in hasura/graphql-engine#4111, it was found out that the new architecture (for which query plan caching wasn't implemented) performed comparably to the pre-PDV architecture with caching. Hence, it was decided to leave query plan caching until some day in the future when it was deemed necessary.

Well, we're in the future now, and there still isn't a convincing argument for query plan caching. So the time has come to remove some references to query plan caching from the codebase. For the most part, any code being removed would probably not be very well suited to the post-PDV architecture of query execution, so arguably not much is lost.

Apart from simplifying the code, this PR will contribute towards making the GraphQL schema generation more modular, testable, and easier to profile. I'd like to eventually work towards a situation in which it's easy to generate a GraphQL schema parser *in isolation*, without being connected to a database, and then parse a GraphQL query *in isolation*, without even listening any HTTP port. It is important that both of these operations can be examined in detail, and in isolation, since they are two major performance bottlenecks, as well as phases where many important upcoming features hook into.

Implementation

The following have been removed:
- The entirety of `server/src-lib/Hasura/GraphQL/Execute/Plan.hs`
- The core phases of query parsing and execution no longer have any references to query plan caching. Note that this is not to be confused with query *response* caching, which is not affected by this PR. This includes removal of the types:
- - `Opaque`, which is replaced by a tuple. Note that the old implementation was broken and did not adequately hide the constructors.
- - `QueryReusability` (and the `markNotReusable` method). Notably, the implementation of the `ParseT` monad now consists of two, rather than three, monad transformers.
- Cache-related tests (in `server/src-test/Hasura/CacheBoundedSpec.hs`) have been removed .
- References to query plan caching in the documentation.
- The `planCacheOptions` in the `TenantConfig` type class was removed. However, during parsing, unrecognized fields in the YAML config get ignored, so this does not cause a breaking change. (Confirmed manually, as well as in consultation with @sordina.)
- The metrics no longer send cache hit/miss messages.

There are a few places in which one can still find references to query plan caching:

- We still accept the `--query-plan-cache-size` command-line option for backwards compatibility. The `HASURA_QUERY_PLAN_CACHE_SIZE` environment variable is not read.

6ed800abaa [gardening] Introduce PartialArbitrary
### Context

One of the ways we use the Backend type families is to use `Void` for all types for which a backend has no representation; this allows us to make some branches of our metadata and IR unrepresentable, making some functions total, where they would have to handle those unsupported cases otherwise.

However, one of the biggest features, functions, cannot be cut that way, due to one of the constraints on `FunctionName b`: the metadata generator requires it to have an `Arbitrary` instance, and `Arbitrary` does not have a recovery mechanism which would allow for a `Void` instance...

### Description

This PR solves this problem and removes the `Arbitrary` constraints in `Backend`. To do so, it introduces a new typeclass: `PartialArbitrary`, which is very similar to `Arbitrary`, except that it returns a `Maybe (Gen a)`, allowing for `Void` to have a well-formed instance. An `Arbitrary` instance for `Metadata` can easily be retrieved with `arbitrary = fromJust . partialArbitrary`.

Furthermore, `PartialArbitrary` has a generic implementation, inspired by the one in `generic-arbitrary`, which automatically prunes branches that return `Nothing`, allowing to automatically construct most types. Types that don't have a type parameter and therefore can't contain `Void` can easily get their `PartialArbitrary` instance from `Arbitrary` with `partialArbitrary = Just arbitrary`. This is what a default overlappable instance provides.

In conjunction with other cleanups in #1666, **this allows for Void function names**.

### Notes

While this solves the stated problem, there are other possible solutions we could explore, such as:
- switching from QuickCheck to a library that supports that kind of pruning natively
- removing the test altogether, and dropping all notion of Arbitrary from the code

There are also several things we could do with the Generator module:
- move it out of RQL.DDL.Metadata, to some place that makes more sense
- move ALL Arbitrary instances in the code to it, since nothing else uses Arbitrary
- or, to the contrary, move all those Arbitrary instances alongside their types, to avoid an orphan instance

e8e4f30dd6 server: support remote relationships on SQL Server and BigQuery (#1497)
Remote relationships are now supported on SQL Server and BigQuery. The major change though is the re-architecture of remote join execution logic. Prior to this PR, each backend is responsible for processing the remote relationships that are part of their AST.

This is not ideal as there is nothing specific about a remote join's execution that ties it to a backend. The only backend specific part is whether or not the specification of the remote relationship is valid (i.e, we'll need to validate whether the scalars are compatible).

The approach now changes to this:

1. Before delegating the AST to the backend, we traverse the AST, collect all the remote joins while modifying the AST to add necessary join fields where needed.

1. Once the remote joins are collected from the AST, the database call is made to fetch the response. The necessary data for the remote join(s) is collected from the database's response and one or more remote schema calls are constructed as necessary.

1. The remote schema calls are then executed and the data from the database and from the remote schemas is joined to produce the final response.

### Known issues

1. Ideally the traversal of the IR to collect remote joins should return an AST which does not include remote join fields. This operation can be type safe but isn't taken up as part of the PR.

1. There is a lot of code duplication between `Transport/HTTP.hs` and `Transport/Websocket.hs` which needs to be fixed ASAP. This too hasn't been taken up by this PR.

1. The type which represents the execution plan is only modified to handle our current remote joins and as such it will have to be changed to accommodate general remote joins.

1. Use of lenses would have reduced the boilerplate code to collect remote joins from the base AST.

1. The current remote join logic assumes that the join columns of a remote relationship appear with their names in the database response. This however is incorrect as they could be aliased. This can be taken up by anyone, I've left a comment in the code.

### Notes to the reviewers

I think it is best reviewed commit by commit.

1. The first one is very straight forward.

1. The second one refactors the remote join execution logic but other than moving things around, it doesn't change the user facing functionality.  This moves Postgres specific parts to `Backends/Postgres` module from `Execute`. Some IR related code to `Hasura.RQL.IR` module.  Simplifies various type class function signatures as a backend doesn't have to handle remote joins anymore

1. The third one fixes partial case matches that for some weird reason weren't shown as warnings before this refactor

1. The fourth one generalizes the validation logic of remote relationships and implements `scalarTypeGraphQLName` function on SQL Server and BigQuery which is used by the validation logic. This enables remote relationships on BigQuery and SQL Server.

This is a minor refactor (part of `Internal/Parser.hs` is moved into `Internal/Input.hs`) to remove `Collect.hs-boot` and `Directives.hs-boot` files. Without these changes:
1. Most changes would trigger recompilation from the modules with hs-boot files.
1. haskell-language-server fails for some reason in the presence of hs-boot files.

a935746e17 Integration test improvements (for speed/clarity), also increase polling interval for scheduled events
This claws back ~7min from integration tests (run serially, as with `dev.sh test --integration`
Further improvements would do well to focus on optimizing metadata operations, as `setup` dominates

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

06b599b747 server: multitenant metadata storage
The metadata storage implementation for graphql-engine-multitenant.

- It uses a centralized PG database to store metadata of all tenants (instead of per tenant database)
- Similarly, it uses a single schema-sync listener thread per MT worker (instead of listener thread per tenant) (PS: although, the processor thread is spawned per tenant)
- 2 new flags are introduced - `--metadataDatabaseUrl` and (optional) `--metadataDatabaseRetries`

Internally, a "metadata mode" is introduced to indicate an external/managed store vs a store managed by each pro-server.

To run :
- obtain the schema file (located at `pro/server/res/cloud/metadata_db_schema.sql`)
- apply the schema on a PG database
- set the `--metadataDatabaseUrl` flag to point to the above database
- run the MT executable

The schema (and its migrations) for the metadata db is managed outside the MT worker.

### New metadata

The following is the new portion of `Metadata` added :

```yaml
version: 3
metrics_config:
  analyze_query_variables: true
  analyze_response_body: false
api_limits:
  disabled: false
  depth_limit:
    global: 5
    per_role:
      user: 7
      editor: 9
  rate_limit:
    per_role:
      user:
        unique_params:
        - x-hasura-user-id
        - x-hasura-team-id
        max_reqs_per_min: 20
    global:
      unique_params: IP
      max_reqs_per_min: 10
```

- In Pro, the code around fetching/updating/syncing pro-config is removed
- That also means, `hdb_pro_catalog` for keeping the config cache is not required. Hence the `hdb_pro_catalog` is also removed
- The required config comes from metadata / schema cache

### New Metadata APIs

- `set_api_limits`
- `remove_api_limits`
- `set_metrics_config`
- `remove_metrics_config`

#### `set_api_limits`

```yaml
type: set_api_limits
args:
  disabled: false
  depth_limit:
    global: 5
    per_role:
      user: 7
      editor: 9
  rate_limit:
    per_role:
      anonymous:
         max_reqs_per_min: 10
         unique_params: "ip"
      editor:
        max_reqs_per_min: 30
        unique_params:
        - x-hasura-user-id
      user:
        unique_params:
        - x-hasura-user-id
        - x-hasura-team-id
        max_reqs_per_min: 20
    global:
      unique_params: IP
      max_reqs_per_min: 10
```

#### `remove_api_limits`

```yaml
type: remove_api_limits
args: {}
```

#### `set_metrics_config`

```yaml
type: set_metrics_config
args:
  analyze_query_variables: true
  analyze_response_body: false
```

#### `remove_metrics_config`

```yaml
type: remove_metrics_config
args: {}
```

#### TODO
- [x] on-prem pro implementation for `MonadMetadataStorage`
- [x] move the project config from Lux to pro metadata (PR: #379)
- [ ] console changes for pro config/api limits, subscription workers (cc @soorajshankar @beerose)
