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

GitOrigin-RevId: 4d4ee6ac8b5506603e70e4fc666a3aacc054d493
### Description
Several libraries define `catMaybes` as `mapMaybe id`. We had it defined in `Data.HashMap.Strict.Extended` already. This small PR also defines it in `Extended` modules for other containers and replaces every occurrence of `mapMaybe id` accordingly.

### 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*`

The only purpose was enabling the developer API by default. I don't
think that justifies a flag and CPP usage.

No logic in this PR, just tidying things up (renaming the backend from `Experimental` to `DataWrapper`).

## Description
This PR is in reference to #2449 (support IP blacklisting for multitenant)
*RFC Update: Add support for IPv6 blocking*
### Solution and Design
Using [http-client-restricted](https://hackage.haskell.org/package/http-client-restricted) package, we're creating the HTTP manager with restricting capabilities. The IPs can be supplied from the CLI arguments as `--ipv4BlocklistCidrs cidr1, cidr2...` or `--disableDefaultIPv4Blocklist` for a default IP list. The new manager will block all requests to the provided CIDRs.
We are extracting the error message string to show the end-user that given IP is blocked from being set as a webhook. There are 2 ways to extract the error message "connection to IP address is blocked". Given below are the responses from event trigger to a blocked IP for these implementations:
- 6d74fde316f61e246c861befcca5059d33972fa7 - We return the error message string as a HTTPErr(HOther) from `Hasura/Eventing/HTTP.hs`.
```
{
"data": {
"message": "blocked connection to private IP address "
},
"version": "2",
"type": "client_error"
}
```
- 88e17456345cbb449a5ecd4877c84c9f319dbc25 - We case match on HTTPExceptionContent for InternaException in `Hasura/HTTP.hs` and extract the error message string from it. (this is implemented as it handles all the cases where pro engine makes webhook requests)
```
{
"data": {
"message": {
"type": "http_exception",
"message": "blocked connection to private IP address ",
"request": {
"secure": false,
"path": "/webhook",
"responseTimeout": "ResponseTimeoutMicro 60000000",
"queryString": "",
"method": "POST",
"requestHeaders": {
"Content-Type": "application/json",
"X-B3-ParentSpanId": "5ae6573edb2a6b36",
"X-B3-TraceId": "29ea7bd6de6ebb8f",
"X-B3-SpanId": "303137d9f1d4f341",
"User-Agent": "hasura-graphql-engine/cerebushttp-ip-blacklist-a793a0e41-dirty"
},
"host": "139.59.90.109",
"port": 8000
}
}
},
"version": "2",
"type": "client_error"
}
```
### Steps to test and verify
The restricted IPs can be used as webhooks in event triggers, and hasura will return an error message in reponse.
### Limitations, known bugs & workarounds
- The `http-client-restricted` has a needlessly complex interface, and puts effort into implementing proxy support which we don't want, so we've inlined a stripped down version.
- Performance constraint: As the blocking is checked for each request, if a long list of blocked CIDRs is supplied, iterating through all of them is not what we would prefer. Using trie is suggested to overcome this. (Added to RFC)
- Calls to Lux endpoints are inconsistent: We use either the http manager from the ProServeCtx which is unrestricted, or the http manager from the ServeCtx which is restricted (the latter through the instances for MonadMetadataApiAuthorization and UserAuthentication). (The failure scenario here would be: cloud sets PRO_ENDPOINT to something that resolves to an internal address, and then restricted requests to those endpoints fail, causing auth to fail on user requests. This is about HTTP requests to lux auth endpoints.)

TL;DR
---
We go from this:
```haskell
(|
withRecordInconsistency
( (|
modifyErrA
( do
(info, dependencies) <- liftEitherA -< buildRelInfo relDef
recordDependencies -< (metadataObject, schemaObject, dependencies)
returnA -< info
)
|) (addTableContext @b table . addRelationshipContext)
)
|) metadataObject
```
to this:
```haskell
withRecordInconsistencyM metadataObject $ do
modifyErr (addTableContext @b table . addRelationshipContext) $ do
(info, dependencies) <- liftEither $ buildRelInfo relDef
recordDependenciesM metadataObject schemaObject dependencies
return info
```
Background
---
We use Haskell's `Arrows` language extension to gain some syntactic sugar when working with `Arrow`s. `Arrow`s are a programming abstraction comparable to `Monad`s.
Unfortunately the syntactic sugar provided by this language extension is not very sweet.
This PR shows how we can sometimes avoid using `Arrow`s altogether, without loss of functionality or correctness. It is a demo of a technique that can be used to cut down the amount of `Arrows`-based code in our codebase by about half.
Approach
---
Although _in general_ not every `Monad` is an `Arrow`, specific `Arrow` instantiations are exactly as powerful as their `Monad` equivalents. Otherwise they wouldn't be very equivalent, would they?
Just like `liftEither` interprets the `Either e` monad into an arbitrary monad implementing `MonadError e`, we add `interpA` which interprets certain concrete monads such as `Writer w` into specific arrows, e.g. ones satisfying `ArrowWriter w`. This means that the part of the code that only uses such interpretable effects can be written _monadically_, and then used in _arrow_ constructions down the line.
This approach cannot be used for arrow effects which do not have a monadic equivalent. In our codebase, the only instance of this is `ArrowCache m`, implemented by the `Rule m` arrow. So code written with `ArrowCache m` in the context cannot be rewritten monadically using this technique.

## Description
Hopefully this is relatively self-explanatory: this change splits the helper functions we've used to extend QuickCheck from the orphan instances and generators that we have defined for unit tests. These have now been placed in `Test.QuickCheck.Extended` and `Hasura.QuickCheck.Instances`, respectively.
This change also adds some documentation to the functions defined in `Test.QuickCheck.Extended` in the spirit of similar functions defined by `Test.QuickCheck`, itself.
### Motivation
We should adhere to the existing convention of constructing "extension modules" for common libraries separately from the code that takes advantage of these.
Alone, this wouldn't be a reason to split up `Hasura.Generators`, but we should **also** follow a convention of defining **all** orphan instances in modules whose names clearly indicate that they exist solely for the purpose of exporting these orphan instances (e.g. `Hasura.QuickCheck.Instances`).

## 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.

## 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`

This commit introduces an "experimental" backend adapter to the GraphQL Engine.
It defines a high-level interface which will eventually be used as the basis for implementing separate data source query generation & marshaling services that communicate with the GraphQL Engine Server via some protocol.

This PR pretty much does the same thing to remote relationship types in schemacache as what #2979 did to remote relationship types in the IR. On main remote relationships are represented by types of form `T from to`. This PR changes it to `T from` which makes it a lot more reusable.

## 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`

This PR simplifies the types that represent a remote relationship in IR so that they can be reused in other parts (in remote schema types) which could have remote relationships.
The comments on the PR explain the main changes.
