## Description
This PR adds the possibility for hspec tests to start a remote server with a custom schema, using the _morpheus_ library. In addition, it adds:
- X-to-DB object relationships tests
- X-to-DB array relationships tests
- X-to-RS relationships tests
For now, all those X are only postgres, but the tests are written in a way that will allow for it to easily be any other DB, or even remote schemas. The actual tests were taken mostly from #3069.
To achieve this, this PR heavily refactors the test harness. Most importantly: it generalizes the notion of a `Backend` to a notion of generic `Context`, allowing for contexts that are the unions of two backends, or of a backend and a remote schema.

There are three minor cleanups here:
- The first argument to the `setMetadataInCatalog` method is always `Just`. It is thus important to avoid `Maybe`, because this means that a crucial piece of code (saving metadata) is completely untested.
- Rather than spelling them out, we can derive the `Semigroup`/`Monoid` instances for `MetadataModifier` through the `Endo` type.
- I've renamed the name of the getter of the `MetadataModifier` newtype to **r**unMetadataModifier. Using record puns, this allows us to write:
```diff
- putMetadata $ unMetadataModifier metadataModifier metadata
+ putMetadata $ runMetadataModifier metadata
```
which is nicer to read.

#### TODO
- [x] fix `hashable >= 1.3.1` serialization ordering issue [^1]
- `test_graphql_mutations.py::TestGraphQLMutateEnums` was failing
- [x] fix `unordered-containers` serialization ordering issue [^2]
- `test_graphql_queries.py` was failing on Citus
- [ ] verify that no new failures have been introduced
- [ ] open issues to fix the above
- identify test cases that "leak" implementation details by depending on `hashable` instance ordering
- bump `hashable >= 1.3.1` and update test cases with new ordering OR modify them so that ordering is stable
- bump `unordered-containers >= 0.2.15.0` and update test cases with new ordering OR modify them so that ordering is stable
- one of the test cases was failing on string equality comparison for a generated Citus query
- we probably don't want to _actually_ do this unless there are _very specific_ guarantees we want to make about generated query structure

Just what it says on the tin.
https://github.com/hasura/graphql-engine-mono/pull/3538 updated the freeze file a few weeks ago, but it looks like the index state hadn't been updated since December so a lot of stuff that had newer versions didn't get updated.
---
EDIT: I should add, the motivation for doing this in the first place is that `hspec > 2.8.4` now supports specifying filtering spec trees based on patterns provided by the `HSPEC_MATCH` environment variable.
For example, one could have a script that executes the following:
```
HSPEC_MATCH="PostgreSQL" \
ghcid \
--command \
'cabal repl graphql-engine:test:tests-hspec \
--repl-option -O0 \
--repl-option -fobject-code' \
--test "main"
```
...which will loop on typechecking the `tests-hspec` component, and then as soon as it passes (i.e. no warnings or errors) will run _only_ the `PostgreSQL` sub-components.
[^1]: `hashable >= 1.3.1.0` [updated its default salts](https://github.com/haskell-unordered-containers/hashable/pull/196), which [broke serialization ordering](https://github.com/haskell/aeson/issues/837)
[^2]: `unordered-containers >= 0.2.16.0` [introduced changes to some of its internal functions](https://hackage.haskell.org/package/unordered-containers-0.2.16.0/changelog) which seem like they could have affected serialization stability

We build the GraphQL schema by combining building blocks such as `tableSelectionSet` and `columnParser`. These building blocks individually build `{InputFields,Field,}Parser` objects. Those object specify the valid GraphQL schema.
Since the GraphQL schema is role-dependent, at some point we need to know what fragment of the GraphQL schema a specific role is allowed to access, and this is stored in `{Sel,Upd,Ins,Del}PermInfo` objects.
We have passed around these permission objects as function arguments to the schema building blocks since we first started dealing with permissions during the PDV refactor - see hasura/graphql-engine@5168b99e46 in hasura/graphql-engine#4111. This means that, for instance, `tableSelectionSet` has as its type:
```haskell
tableSelectionSet ::
forall b r m n.
MonadBuildSchema b r m n =>
SourceName ->
TableInfo b ->
SelPermInfo b ->
m (Parser 'Output n (AnnotatedFields b))
```
There are three reasons to change this.
1. We often pass a `Maybe (xPermInfo b)` instead of a proper `xPermInfo b`, and it's not clear what the intended semantics of this is. Some potential improvements on the data types involved are discussed in issue hasura/graphql-engine-mono#3125.
2. In most cases we also already pass a `TableInfo b`, and together with the `MonadRole` that is usually also in scope, this means that we could look up the required permissions regardless: so passing the permissions explicitly undermines the "single source of truth" principle. Breaking this principle also makes the code more difficult to read.
3. We are working towards role-based parsers (see hasura/graphql-engine-mono#2711), where the `{InputFields,Field,}Parser` objects are constructed in a role-invariant way, so that we have a single object that can be used for all roles. In particular, this means that the schema building blocks _need_ to be constructed in a role-invariant way. While this PR doesn't accomplish that, it does reduce the amount of role-specific arguments being passed, thus fixing hasura/graphql-engine-mono#3068.
Concretely, this PR simply drops the `xPermInfo b` argument from almost all schema building blocks. Instead these objects are looked up from the `TableInfo b` as-needed. The resulting code is considerably simpler and shorter.
One way to interpret this change is as follows. Before this PR, we figured out permissions at the top-level in `Hasura.GraphQL.Schema`, passing down the obtained `xPermInfo` objects as required. After this PR, we have a bottom-up approach where the schema building blocks themselves decide whether they want to be included for a particular role.
So this moves some permission logic out of `Hasura.GraphQL.Schema`, which is very complex.

## Description
This PR adds all the scaffolding for tests that require remote servers. It is mostly a refactor of `Feature`; where we listed for each test a list of individual backends, we now provide a list of `Context`s, that allows for tests to specify not only how it should be setup, but also what state needs to be carried around throughout the test. This will be useful when launching custom remote servers.
Additionally, this PR:
- cleans the way we generate logs in the engine as part of the tests
- cleans the cabal file
- introduce a few more helpers for sending commands to the engine (such as `postMetadata_`)
- allows for headers in queries sent to the engine (to support permissions tests)
- adds basic code to start / stop a "remote" server
This PR is a pre-requisite of #3567.

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`
