This came about as I tried to add an instance over catalog versions and
found they were just simple integers most of the time (and in one case,
a float).
I think this change also clarifies how catalog versions work.

This implements an initial set of DTO types that represent serialized metadata. These new types come with codecs using autodocodec which are used to derive both JSON serialization, and OpenAPI documentation. This ensures that we can automatically generate API documentation that is guaranteed to match JSON produced by the server.
For the moment the new types are not used for anything except to generate an early version of an OpenAPI document. Because this is early work the DTO types for each metadata format version list top-level properties only with placeholders for the types of each top-level property. This early iteration demonstrates using a sum type in Haskell that maps to a tagged union in OpenAPI (using the `version` field value as a tag).
This work is experimental and incomplete! Please do not incorporate the generated OpenAPI documentation into essential workflows at this time.

### 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`.

With the current implementation, only the first call to `waitForShutdown` on a given
`ShutdownLatch` will return, while others will block (typically indefinitely). That's not
how one would expect a shutdown latch to work.
This isn't currently a concrete issue because we only wait once on each `ShutdownLatch`.
But in the context of #4154 we'll probably end up wanting to wait for shutdown from
multiple threads.
This adds a number of tests to verify the current behaviour, and adds a test for multiple
`waitForShutdown` calls that fails prior to the functional change.

### Description
Despite making sure only a small range was used for each value, this test can nonetheless result in an explosion of memory usage: it has twice in a row resulted in my poor laptop filling its swap in a matter of seconds, forcing me to kill the test or hard-reboot my machine.
This small PR lowers the high bound of the range used for the generator, to a value that seems to consistently allows the test to finish in a more constrained environment.
Additionally, it also sorts the tests alphabetically: it makes it much easier when scrolling through the output to find a specific test.

It makes sense to try to utilize multiple threads for metadata
operations since we expect them to come one at a time (and likely at
lower load periods anyway).
As noted, although we build roles in parallel now, the admin role is
still a bottleneck. For replace_metadata on huge_schema, on my machine

### Description
There were several places in the codebase where we would either implement a generic container, or express the need for one. This PR extracts / creates all relevant containers, and adapts the relevant parts of the code to make use of said new generic containers. More specifically, it introduces the following modules:
- `Data.Set.Extended`, for new functions on `Data.Set`
- `Data.HashMap.Strict.Multi`, for hash maps that accept multiple values
- `Data.HashMap.Strict.NonEmpty`, for hash maps that can never be constructed as empty
- `Data.Trie`, for a generic implementation of a prefix tree
This PR makes use of those new containers in the following parts of the code:
- `Hasura.GraphQL.Execute.RemoteJoin.Types`
- `Hasura.RQL.Types.Endpoint*`

I discovered and removed instances of Boolean Blindness about whether json numbers should be stringified or not.
Although quite far-reaching, this is a completely mechanical change and should have no observable impact outside the server code.

spec: https://github.com/hasura/graphql-engine-mono/pull/2278
Briefly:
- extend metadata so that allowlist entries get a new scope field
- update `add_collection_to_allowlist` to accept this new scope field,
and adds `update_scope_of_collection_in_allowlist` to change the scope
- scope can be global or role-based; a collection is available for every
role if it is global, and available to every listed role if it is role-based
- graphql-engine-oss is aware of role-based allowlist metadata; collections
with non-global scope are treated as if they weren't in the allowlist
To run the tests:
- `cabal run graphql-engine-tests -- unit --match Allowlist`
- py-tests against pro:
- launch `graphql-engine-pro` with `HASURA_GRAPHQL_ADMIN_SECRET` and `HASURA_GRAPHQL_ENABLE_ALLOWLIST`
- `pytest test_allowlist_queries.py --hge-urls=... --pg-urls=... --hge-key=... --test-allowlist-queries --pro-tests`

## Description
This PR fixes two issues:
- in [#2903](https://github.com/hasura/graphql-engine-mono/pull/2903), we introduced a new metadata representation of remote relationships, which broke parsing a metadata blob containing an old-style db-to-rs remote relationship
- in [#1179](https://github.com/hasura/graphql-engine-mono/pull/1179), we silently and mistakenly deprecated `create_remote_relationship` in favour of `<backend>_create_remote_relationship`

# Description
The tests were only being run with fully qualified postgresql and
mssql connection env vars anyhow. Makes it a bit simpler to run the
tests.
- the test suite now requires only plain connection strings as
`HASURA_GRAPHQL_DATABASE_URL` (postgres) or
`HASURA_MSSQL_CONN_STR` (mssql)
- update `CONTRIBUTING.md` for this change, and make it
generally a bit less inaccurate

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.)

This commit applies ormolu to the whole Haskell code base by running `make format`.
For in-flight branches, simply merging changes from `main` will result in merge conflicts.
To avoid this, update your branch using the following instructions. Replace `<format-commit>`
by the hash of *this* commit.
$ git checkout my-feature-branch
$ git merge <format-commit>^ # and resolve conflicts normally
$ make format

This is a follow-up to #1959.
Today, I spent a while in review figuring out that a harmless PR change didn't do anything,
because it was moving from a `runLazy...` to something without the `Lazy`. So let's get
that source of confusion removed.
This should be a bit easier to review commit by commit, since some of the functions had
confusing names. (E.g. there was a misnamed `Migrate.Internal.runTx` before.)
The change should be a no-op.

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.

## Description
Thanks to #1664, the Metadata API types no longer require a `ToJSON` instance. This PR follows up with a cleanup of the types of the arguments to the metadata API:
- whenever possible, it moves those argument types to where they're used (RQL.DDL.*)
- it removes all unrequired instances (mostly `ToJSON`)
This PR does not attempt to do it for _all_ such argument types. For some of the metadata operations, the type used to describe the argument to the API and used to represent the value in the metadata are one and the same (like for `CreateEndpoint`). Sometimes, the two types are intertwined in complex ways (`RemoteRelationship` and `RemoteRelationshipDef`). In the spirit of only doing uncontroversial cleaning work, this PR only moves types that are not used outside of RQL.DDL.
Furthermore, this is a small step towards separating the different types all jumbled together in RQL.Types.
## Notes
This PR also improves several `FromJSON` instances to make use of `withObject`, and to use a human readable string instead of a type name in error messages whenever possible. For instance:
- before: `expected Object for Object, but encountered X`
after: `expected Object for add computed field, but encountered X`
- before: `Expecting an object for update query`
after: `expected Object for update query, but encountered X`
This PR also renames `CreateFunctionPermission` to `FunctionPermissionArgument`, to remove the quite surprising `type DropFunctionPermission = CreateFunctionPermission`.
This PR also deletes some dead code, mostly in RQL.DML.
This PR also moves a PG-specific source resolving function from DDL.Schema.Source to the only place where it is used: App.hs.
