…fix #5426"
This reverts commit f85742318167d1e51f463c45fcd00f26269c2555.
## Description ✍️
With this commit there is the possiblity that you could get conflicting
type definitions with remote schemas. Reverting for now as we determine
a solution. At which point we will add this back in.

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.

The code that builds the GraphQL schema, and `buildGQLContext` in particular, is partial: not every value of `(ServerConfigCtx, GraphQLQueryType, SourceCache, HashMap RemoteSchemaName (RemoteSchemaCtx, MetadataObject), ActionCache, AnnotatedCustomTypes)` results in a valid GraphQL schema. When it fails, we want to be able to return better error messages than we currently do.
The key thing that is missing is a way to trace back GraphQL type information to their origin from the Hasura metadata. Currently, we have a number of correctness checks of our GraphQL schema. But these correctness checks only have access to pure GraphQL type information, and hence can only report errors in terms of that. Possibly the worst is the "conflicting definitions" error, which, in practice, can only be debugged by Hasura engineers. This is terrible DX for customers.
This PR allows us to print better error messages, by adding a field to the `Definition` type that traces the GraphQL type to its origin in the metadata. So the idea is simple: just add `MetadataObjId`, or `Maybe` that, or some other sum type of that, to `Definition`.
However, we want to avoid having to import a `Hasura.RQL` module from `Hasura.GraphQL.Parser`. So we instead define this additional field of `Definition` through a new type parameter, which is threaded through in `Hasura.GraphQL.Parser`. We then define type synonyms in `Hasura.GraphQL.Schema.Parser` that fill in this type parameter, so that it is not visible for the majority of the codebase.
The idea of associating metadata information to `Definition`s really comes to fruition when combined with hasura/graphql-engine-mono#4517. Their combination would allow us to use the API of fatal errors (just like the current `MonadError QErr`) to report _inconsistencies_ in the metadata. Such inconsistencies are then _automatically_ ignored. So no ad-hoc decisions need to be made on how to cut out inconsistent metadata from the GraphQL schema. This will allow us to report much better errors, as well as improve the likelihood of a successful HGE startup.

This has a couple of advantages:
1. One query is probably faster than many.
2. Creating a table with data is valid on the BigQuery sandbox (free tier); `INSERT INTO` is not.
3. We eat fewer resources by not running any DML, and so should hit usage caps less often.

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.

When pytest rewrites assertions to make them more useful, it also
truncates long assertion messages in the middle, often obscuring the
actual error.
Disabling this allows us to see the full message, which should hopefully
allow us to see the actual error.
In order to support this, we need to make sure that custom assertion
messages include the actual assertion information, as this will no
longer be rendered by pytest.

### Description
This PR removes the need for the `SourceCache` when building the schema for the actions. To do so, it changes the way we represent custom types in the source cache. Instead of trying to reuse the same `ObjectTypeDefinition` and `TypeRelationship`. we now have separate `AnnotatedObjectType` and `AnnotatedRelationship`. When building them, at schema cache building time, we persist all the relevant source information, so that it's all available at schema building time.
This PR makes no attempt at re-using `RemoteRelationship` primitives, to avoid having to change the way async action queries are executed, and to avoid having to make complicated changes to how we parse and represent those relationships.

Pretty much all quasi-quoted names in the server code base have ended up in `Hasura.GraphQL.Parser.Constants`. I'm now finding this unpleasant for two reasons:
1. I would like to factor out the parser code into its own Cabal package, and I don't want to have to expose all these names.
2. Most of them really have nothing to do with the parsers.
In order to remedy this, I have:
1. moved the names used by parser code to `Hasura.GraphQL.Parser.DirectiveName`, as they're all related to directives;
2. moved `Hasura.GraphQL.Parser.Constants` to `Hasura.Name`, changing the qualified import name from `G` to `Name`;
3. moved names only used in tests to the appropriate test case;
4. removed unused items from `Hasura.Name`; and
5. grouped related names.
Most of the changes are simply changing `G` to `Name`, which I find much more meaningful.

### Description
This small clean-up PR makes one further step towards backend-agnostic actions: it makes all the code parsing custom types backend agnostic. Surprisingly, this could be done *without* the need to finish generalizing the column parser. The remaining sore point is async queries, that still target Postgres explicitly.
In theory, this is enough to start allowing non-Postgres scalars in custom types. In practice, however:
- no other backend exposes scalars in a way that would allow users to do that as of this PR;
- we currently have no strategy to avoid / detect scalar collisions across backends.

You can now run `nix fmt` (or `make format-changed`) to reformat Nix
files.
This is not enforced by CI.

This aims to support loading up a `ghci repl` with both the `graphql-engine` library and the unit tests. This is currently not officially supported by cabal, but it uses a hack, which is why I added a flag. See the updated documentation for more info.

## Description ✍️
->
Fleshes out the Capabilities types used by Data Connector agents.
### Related Issues ✍
->
https://hasurahq.atlassian.net/browse/GDW-85
### Solution and Design ✍
>
Capabilities are divided into sections for queries, mutation, subscriptions, filtering and relationships:
```haskell
data Capabilities = Capabilities
{ cQueries :: Maybe QueryCapabilities,
cMutations :: Maybe MutationCapabilities,
cSubscriptions :: Maybe SubscriptionCapabilities,
cFiltering :: Maybe FilteringCapabilities,
cRelationships :: Maybe RelationshipCapabilities
}
```
Each section is optional. If the section is absent it means the the related capabilities are not supported by the agent.
The types for each section can contain additional details about exactly what is supported. E.g.
```haskell
data QueryCapabilities = QueryCapabilities
{ qcSupportsPrimaryKeys :: Bool
}
```
These are currently mostly empty, but will be filled in later.
