### Description
If i understand correctly, the _value_ of a feature flag **can** change at runtime. Since this has an impact on how the schema cache is built, this PR makes the value of the flag a part of the cache's "dynamic" config, therefore making it an arrow-ish argument for the incremental framework. It also removes `CheckFeatureFlag` from the static config, now obsolete.

### Description
This PR removes `ServerConfigCtx` and `HasServerConfigCtx`. Instead, it favours different approaches:
- when the code was only using one field, it passes that field explicitly (usually `SQLGenCtx` or `CheckFeatureFlag`)
- when the code was using several fields, but in only one function, it inlines
- for the cache build, it introduces `CacheStaticConfig` and `CacheDynamicConfig`, which are subsets of `AppEnv` and `AppContext` respectively
The main goal of this is to help with the modularization of the engine: as `ServerConfigCtx` had fields whose types were imported from several unrelated parts of the engine, using it tied together parts of the engine that should not be aware of one another (such as tying together `Hasura.LogicalModel` and `Hasura.GraphQL.Schema`).
The bulk of this PR is a change to the cache build, as a follow up to #8509: instead of giving the entire `ServerConfigCtx` as a incremental rule argument, we only give the new `CacheDynamicConfig` struct, which has fewer fields. The other required fields, that were coming from the `AppEnv`, are now given via the `HasCacheStaticConfig` constraint, which is a "subset" of `HasAppEnv`.
(Some further work could include moving `StringifyNumbers` out of `GraphQL.Schema.Options`, given how it is used all across the codebase, including in `RQL.DML`.)

## Description
This PR is a incremental step towards achieving the goal of #8344. It is a less ambitious version of #8484.
This PR removes all references to `HasServerConfigCtx` from the cache build and removes `ServerConfigCtx` from `CacheBuildParams`, making `ServerConfigCtx` an argument being passed around manually instead. This has several benefits: by making it an arrow argument, we now properly integrate the fields that change over time in the dependency framework, as they should be, and we can clean up some of the top-level app code.
## Implementation
In practice, this PR introduces a `HasServerConfigCtx` instance for `CacheRWT`, the monad we use to build the cache, so we can retrieve the `ServerConfigCtx` in the implementation of `CacheRWM`. This contributes to reducing the amount of `HasServerConfigCtx` in the code: we can remove `SchemaUpdateT` altogether, and we can remove the `HasServerConfigCtx` instance of `Handler`. This makes `HasServerConfigCtx` almost **an implementation detail of the Metadata API**.
This first step is enough to achieve the goal of #8344: we can now build the schema cache in the app monad, since we no longer rely on `HasServerConfigCtx` to build it.
## Drawbacks
This PR does not attempt to remove the use of `ServerConfigCtx` itself in the schema cache build: doing so would make this PR much much bigger. Ideally, to avoid having all the static fields given as arrow-ish arguments to the cache, we could depend on `HasAppEnv` in the cache build, and use `AppContext` as an arrow argument. But making the cache build depend on the full `AppEnv` and `AppContext` creates a lot of circular imports; and since removing `ServerConfigCtx` itself isn't required to achieve #8344, this PR keeps it wholesale and defers cleaning it to a future PR.
A negative consequence of this is that we need an `Eq` instance on `ServerConfigCtx`, and that instance is inelegant.
## Future work
There are several further steps we can take in parallel after this is merged. First, again, we can make a new version of #8344, removing `CacheBuild`, FINALLY. As for `ServerConfigCtx`, we can split it / rename it to make ad-hoc structures. If it turns out that `ServerConfigCtx` is only ever used for the schema cache build, we could split it between `CacheBuildEnv` and `CacheBuildContext`, which will be subsets of `AppEnv` and `AppContext`, avoiding import loops.

## Description
This PR does several different things that happen to overlap; the most important being:
- it removes `RunT`: it was redundant in places where we already had `Handler`, and only used in one other place, `SchemaUpdate`, for which a local `SchemaUpdateT` is more than enough;
- it reduces the number of places where we create a `ServerConfigCtx`, since now `HasServerConfigCtx` can be implemented directly by `SchemaUpdateT` and `Handler` based on the full `AppContext`;
- it drastically reduces the number of arguments we pass around in the app init code, by introducing `HasAppEnv`;
- it simplifies `HandlerCtx` to reduce duplication
In doing so, this changes paves the way towards removing `ServerConfigCtx`, since there are only very few places where we construct it: we can now introduce smaller classes than `HasServerConfigCtx`, that expose only a relevant subset of fields, and implement them where we now implement `HasServerConfigCtx`.
This PR is loosely based on ideas in #8337, that are no longer applicable due to the changes introduced in #8159. A challenge of this PR was the postgres tests, which were running in `PGMetadataStorageAppT CacheBuild` 🙀

## Description
### I want to speak to the `Manager`
Oh boy. This PR is both fairly straightforward and overreaching, so let's break it down.
For most network access, we need a [`HTTP.Manager`](https://hackage.haskell.org/package/http-client-0.1.0.0/docs/Network-HTTP-Client-Manager.html). It is created only once, at the top level, when starting the engine, and is then threaded through the application to wherever we need to make a network call. As of main, the way we do this is not standardized: most of the GraphQL execution code passes it "manually" as a function argument throughout the code. We also have a custom monad constraint, `HasHttpManagerM`, that describes a monad's ability to provide a manager. And, finally, several parts of the code store the manager in some kind of argument structure, such as `RunT`'s `RunCtx`.
This PR's first goal is to harmonize all of this: we always create the manager at the root, and we already have it when we do our very first `runReaderT`. Wouldn't it make sense for the rest of the code to not manually pass it anywhere, to not store it anywhere, but to always rely on the current monad providing it? This is, in short, what this PR does: it implements a constraint on the base monads, so that they provide the manager, and removes most explicit passing from the code.
### First come, first served
One way this PR goes a tiny bit further than "just" doing the aforementioned harmonization is that it starts the process of implementing the "Services oriented architecture" roughly outlined in this [draft document](https://docs.google.com/document/d/1FAigqrST0juU1WcT4HIxJxe1iEBwTuBZodTaeUvsKqQ/edit?usp=sharing). Instead of using the existing `HasHTTPManagerM`, this PR revamps it into the `ProvidesNetwork` service.
The idea is, again, that we should make all "external" dependencies of the engine, all things that the core of the engine doesn't care about, a "service". This allows us to define clear APIs for features, to choose different implementations based on which version of the engine we're running, harmonizes our many scattered monadic constraints... Which is why this service is called "Network": we can refine it, moving forward, to be the constraint that defines how all network communication is to operate, instead of relying on disparate classes constraint or hardcoded decisions. A comment in the code clarifies this intent.
### Side-effects? In my Haskell?
This PR also unavoidably touches some other aspects of the codebase. One such example: it introduces `Hasura.App.AppContext`, named after `HasuraPro.Context.AppContext`: a name for the reader structure at the base level. It also transforms `Handler` from a type alias to a newtype, as `Handler` is where we actually enforce HTTP limits; but without `Handler` being a distinct type, any code path could simply do a `runExceptT $ runReader` and forget to enforce them.
(As a rule of thumb, i am starting to consider any straggling `runReaderT` or `runExceptT` as a code smell: we should not stack / unstack monads haphazardly, and every layer should be an opaque `newtype` with a corresponding run function.)
## Further work
In several places, i have left TODOs when i have encountered things that suggest that we should do further unrelated cleanups. I'll write down the follow-up steps, either in the aforementioned document or on slack. But, in short, at a glance, in approximate order, we could:
- delete `ExecutionCtx` as it is only a subset of `ServerCtx`, and remove one more `runReaderT` call
- delete `ServerConfigCtx` as it is only a subset of `ServerCtx`, and remove it from `RunCtx`
- remove `ServerCtx` from `HandlerCtx`, and make it part of `AppContext`, or even make it the `AppContext` altogether (since, at least for the OSS version, `AppContext` is there again only a subset)
- remove `CacheBuildParams` and `CacheBuild` altogether, as they're just a distinct stack that is a `ReaderT` on top of `IO` that contains, you guessed it, the same thing as `ServerCtx`
- move `RunT` out of `RQL.Types` and rename it, since after the previous cleanups **it only contains `UserInfo`**; it could be bundled with the authentication service, made a small implementation detail in `Hasura.Server.Auth`
- rename `PGMetadaStorageT` to something a bit more accurate, such as `App`, and enforce its IO base
This would significantly simply our complex stack. From there, or in parallel, we can start moving existing dependencies as Services. For the purpose of supporting read replicas entitlement, we could move `MonadResolveSource` to a `SourceResolver` service, as attempted in #7653, and transform `UserAuthenticationM` into a `Authentication` service.

## Description
This PR removes `MetadataStorageT`, and cleans up all top-level error handling. In short: this PR changes `MonadMetadataStorage` to explicitly return a bunch of `Either QErr a`, instead of relying on the stack providing a `MonadError QErr`. Since we implement that class on the base monad *below any ExceptT*, this removes a lot of very complicated instances that make assumptions about the shape of the stack.
On the back of this, we can remove several layers of ExceptT from the core of the code, including the one in `RunT`, which allows us to remove several instances of `liftEitherM . runExceptT`.

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.

Result of executing the following commands:
```shell
# replace "as Q" imports with "as PG" (in retrospect this didn't need a regex)
git grep -lE 'as Q($|[^a-zA-Z])' -- '*.hs' | xargs sed -i -E 's/as Q($|[^a-zA-Z])/as PG\1/'
# replace " Q." with " PG."
git grep -lE ' Q\.' -- '*.hs' | xargs sed -i 's/ Q\./ PG./g'
# replace "(Q." with "(PG."
git grep -lE '\(Q\.' -- '*.hs' | xargs sed -i 's/(Q\./(PG./g'
# ditto, but for [, |, { and !
git grep -lE '\[Q\.' -- '*.hs' | xargs sed -i 's/\[Q\./\[PG./g'
git grep -l '|Q\.' -- '*.hs' | xargs sed -i 's/|Q\./|PG./g'
git grep -l '{Q\.' -- '*.hs' | xargs sed -i 's/{Q\./{PG./g'
git grep -l '!Q\.' -- '*.hs' | xargs sed -i 's/!Q\./!PG./g'
```
(Doing the `grep -l` before the `sed`, instead of `sed` on the entire codebase, reduces the number of `mtime` updates, and so reduces how many times a file gets recompiled while checking intermediate results.)
Finally, I manually removed a broken and unused `Arbitrary` instance in `Hasura.RQL.Network`. (It used an `import Test.QuickCheck.Arbitrary as Q` statement, which was erroneously caught by the first find-replace command.)
After this PR, `Q` is no longer used as an import qualifier. That was not the goal of this PR, but perhaps it's a useful fact for future efforts.

We only use these `Show` instances in error messages (where we call
`show` explicitly anyway) and test cases (in which Hspec requires `Show
a` for any `a` in an assertion).
This removes the instance in favor of a custom `showQErr` function
(which serializes the error to JSON). It is then used in certain error
message production which previously called `show` on a `QErr`.
There are two places where we serialize a QErr and then construct a new
QErr from the resulting string. Instead, we modify the existing QErr to
add extra information.
An orphan `Show QErr` instance is retained for tests so that we can have
nice test failure messages.
This is preparation for future changes in which the error message within
`QErr` will not be exposed directly, and therefore will not have a
`Show` instance. That said, it feels like a sensible kind of cleanup
anyway.

Removing `schemaSyncDisable` flag and interpreting `schemaPollInterval` of `0` as disabling schema sync.
This change brings the convention in line with how action and other intervals are used to disable processes.
There is an opportunity to abstract the notion of an optional interval similar to how actions uses `AsyncActionsFetchInterval`.
This can be used for the following fields of ServeOptions, with RawServeOptions having a milliseconds value where `0` is interpreted as disable.
OptionalInterval:
```
-- | Sleep time interval for activities
data OptionalInterval
= Skip -- ^ No polling
| Interval !Milliseconds -- ^ Interval time
deriving (Show, Eq)
```
ServeOptions:
```
data ServeOptions impl
= ServeOptions
{
...
, soEventsFetchInterval :: !OptionalInterval
, soAsyncActionsFetchInterval :: !OptionalInterval
, soSchemaPollInterval :: !OptionalInterval
...
}
```
Rather than encoding a `Maybe OptionalInterval` in RawServeOptions, instead a `Maybe Milliseconds` can be used to more directly express the input format, with the ServeOptions constructor interpreting `0` as `Skip`.
Current inconsistencies:
* `soEventsFetchInterval` has no value interpreted as disabling the fetches
* `soAsyncActionsFetchInterval` uses an `OptionalInterval` analog in `RawServeOptions` instead of `Milliseconds`
* `soSchemaPollInterval` currently uses `Milliseconds` directly in `ServeOptions`

Modifying schema-sync implementation to use polling for OSS/Pro. Invalidations are now propagated via the `hdb_catalog.hdb_schema_notifications` table in OSS/Pro. Pattern followed is now a Listener/Processor split with Cloud listening for changes via a LISTEN/NOTIFY channel and OSS polling for resource version changes in the metadata table. See issue #460 for more details.

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

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

Introspection queries accept variables, but we need to make sure to

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.

* 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.

These must have gotten messed up during a refactor. As a consequence
almost all samples received so far fall into the single erroneous 0 to
1K seconds (originally supposed to be 1ms?) bucket.
I also re-thought what the numbers should be, but these are still
arbitrary and might want adjusting in the future.

!!! 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)
* [skip ci] Fix accumulation of input object types
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).

As we need to log all messages recieved/sent by the websocket server,
it makes sense to log them as part of the websocket server event logs.
Previously message recieved were logged inside the onMessage handler,
and messages sent were logged only for "data" messages (as a server event log)

* [skip ci] update commit_diff with new commits added in master
* Bugfix to support 0-size HASURA_GRAPHQL_QUERY_PLAN_CACHE_SIZE
Also some minor refactoring of bounded cache module:
- the maxBound check in `trim` was confusing and unnecessary
- consequently trim was unnecessary for lookupPure
Also add some basic tests
* Support only the bounded cache, with default HASURA_GRAPHQL_QUERY_PLAN_CACHE_SIZE of 4000. Closes#5363

* [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.

* [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.

* fix 'ID' input coercing & action 'ID' type relationship mapping

* 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/66https://github.com/palantir/bulldozer/issues/145
* Cherry-picked all commits
* [skip ci] Slightly improve formatting

This undoes a cherry-pick of 34288e1eb5 that was
already done previously in a6450e126b, and
subsequently fixed for PDV in 70e89dc250
