It might be interesting to think about taking into consideration decompression time when thinking about performance, but In general I think doing so is surprising and I wasted a lot of time trying to figure out why my optimizations to the compression codepath weren't improving things to the degree I expected
The downside here is we lose error reporting, so you'll need to only set
discardResponseBodies: true after the query has been tested.

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.

This fixes a few issues so that we can run `./server/tests-py/run.sh backend-bigquery` to run the Python integration tests for BigQuery locally.
* We forward the relevant environment variables to the Docker container.
* We increase the HTTP timeout, as I'm seeing requests taking up to 90s locally.
* We rewrite the setup so that it avoids `INSERT INTO`, which is not available using the BigQuery free tier. Instead, we use `CREATE TABLE ... AS SELECT ...`. This is the same method used by the Haskell integration tests.
We also capture local server output in a volume so it's easier to figure out what went wrong later.

I am working on https://github.com/hasura/graphql-engine/issues/8807, and wanted to write a Haskell integration test case to reproduce it.
We have Python integration tests somewhat covering this behavior in *test_inconsistent_meta.py*, but no Haskell tests, so I thought I'd shore up the coverage here by adding a few test cases for working behavior.

This makes two changes to the Docker Compose files that we use for local testing:
1. We disable `fsync`. On my machine, this decreases the time taken to create a new database from ~5s to less than 0.1s. The trade-off is that you might lose data, which we don't care about, as this is for testing.
2. We increase the maximum number of connections from the default, 100, to 1000. This allows us to run more tests in parallel without hitting connection limits.
These changes won't have any meaningful effect for now; they simply allow us to parallelize tests against PostgreSQL in the future.

This argument allows the user to specify how to run HGE, rather than starting it beforehand. The runner will start a new instance of HGE for each test class.
This does not provide isolation, as the database is still re-used, but it helps us get closer.
You can try it yourself by executing:
```
$ cabal build graphql-engine:exe:graphql-engine
$ ./server/tests-py/run-new.sh
```
This doesn't affect CI at all.
I also fixed a few warnings flagged by Pylance.

The intent is to generalize `columnParser` to the point where it is the same across all backends, and then remove the interface in favor of a single implementation.
This extracts out `enumParser` and `possiblyNullable` as the two main areas that differ across backends. We may split `possiblyNullable` further so that we can extract some of that logic out into a common function too.
With these changes, the various `columnParser` implementations become semantically equivalent. They still do different things, and so reconciling them will require further changes.

### Description
This PR attempts to fix several issues with source customization as it relates to remote relationships. There were several issues regarding casing: at the relationship border, we didn't properly set the target source's case, we didn't have access to the list of supported features to decide whether the feature was allowed or not, and we didn't have access to the global default.
However, all of that information is available when we build the schema cache, as we do resolve the case of some elements such as function names: we can therefore resolve source information at the same time, and simplify both the root of the schema and the remote relationship border.
To do this, this PR introduces a new type, `ResolvedSourceCustomization`, to be used in the Schema Cache, as opposed to the metadata's `SourceCustomization`, following a pattern established by a lot of other types.
### Remaining work and open questions
One major point of confusion: it seems to me that we didn't set the case at all across remote relationships, which would suggest we would use the case of the LHS source across the subset of the RHS one that is accessible through the remote relationship, which would in turn "corrupt" the parser cache and might result in the wrong case being used for that source later on. Is that assesment correct, and was I right to fix it?
Another one is that we seem not to be using the local case of the RHS to name the field in an object relationship; unless I'm mistaken we only use it for array relationships? Is that intentional?
This PR is also missing tests that would show-case the difference, and a changelog entry. To my knowledge, all the tests of this feature are in the python test suite; this could be the opportunity to move them to the hspec suite, but this might be a considerable amount of work?

This allows a developer, through Docker, to run the Python integration tests in pretty much exactly the same way as CI does.
Allowing us to more readily diagnose issues locally.
I'm hoping this is temporary and we won't need it for too long, but I have found it invaluable over the last few days so I would like to share it.

This abstracts `CircularT`'s test cases to work against "any" memoizer, and then runs them against `MemoizeT` as well.
Surprisingly (or not), this works without issue; `MemoizeT` passes all tests with a couple of extra instances.

Where possible, we start the services on random ports, to avoid
port conflicts when parallelizing tests in the future.
When this isn't possible, we explicitly state the port, and wait for the
service to start. This is typically because the GraphQL Engine has already
started with knowledge of the relevant service passed in through an
environment variable.

### Description
This PR changes all the schema code to operate in a specific `SchemaT` monad, rather than in an arbitrary `m` monad. `SchemaT` is intended to be used opaquely with `runSourceSchema` and `runRemoteSchema`. The main goal of this is to allow a different reader context per part of the schema: this PR also minimizes the contexts. This means that we no longer require `SchemaOptions` when building remote schemas' schema, and this PR therefore removes a lot of dummy / placeholder values accordingly.
### Performance and stacking
This PR has been through several iterations. #5339 was the original version, that accomplished the same thing by stacking readers on top of the stack at every remote relationship boundary. This raised performance concerns, and @0x777 confirmed with an ad-hoc test that in some extreme cases we could see up to a 10% performance impact. This version, while more verbose, allows us to unstack / re-stack the readers, and avoid that problem. #5517 adds a new benchmark set to be able to automatically measure this on every PR.
### Remaining work
- [x] a comment (or perhaps even a Note?) should be added to `SchemaT`
- [x] we probably want for #5517 to be merged first so that we can confirm the lack of performance penalty

This PR expands the OpenAPI specification generated for metadata to include separate definitions for `SourceMetadata` for each native database type, and for DataConnector.
For the most part the changes add `HasCodec` implementations, and don't modify existing code otherwise.
The generated OpenAPI spec can be used to generate TypeScript definitions that distinguish different source metadata types based on the value of the `kind` properly. There is a problem: because the specified `kind` value for a data connector source is any string, when TypeScript gets a source with a `kind` value of, say, `"postgres"`, it cannot unambiguously determine whether the source is postgres, or a data connector. For example,
```ts
function consumeSourceMetadata(source: SourceMetadata) {
if (source.kind === "postgres" || source.kind === "pg") {
// At this point TypeScript infers that `source` is either an instance
// of `PostgresSourceMetadata`, or `DataconnectorSourceMetadata`. It
// can't narrow further.
source
}
if (source.kind === "something else") {
// TypeScript infers that this `source` must be an instance of
// `DataconnectorSourceMetadata` because `source.kind` does not match
// any of the other options.
source
}
}
```
The simplest way I can think of to fix this would be to add a boolean property to the `SourceMetadata` type along the lines of `isNative` or `isDataConnector`. This could be a field that only exists in serialized data, like the metadata version field. The combination of one of the native database names for `kind`, and a true value for `isNative` would be enough for TypeScript to unambiguously distinguish the source kinds.
But note that in the current state TypeScript is able to reference the short `"pg"` name correctly!
~~Tests are not passing yet due to some discrepancies in DTO serialization vs existing Metadata serialization. I'm working on that.~~
The placeholders that I used for table and function metadata are not compatible with the ordered JSON serialization in use. I think the best solution is to write compatible codecs for those types in another PR. For now I have disabled some DTO tests for this PR.
Here are the generated [OpenAPI spec](https://github.com/hasura/graphql-engine-mono/files/9397333/openapi.tar.gz) based on these changes, and the generated [TypeScript client code](https://github.com/hasura/graphql-engine-mono/files/9397339/client-typescript.tar.gz) based on that spec.

### Description
This PR adds a new benchmarl set named `deep_schema`, that is made to replicate one very specific edge-case: schemas that have deeply nested remote relationships. Our schema-building code is, in essence, "depth-first", and there are a lot of subtleties in the way we jump across remote relationship boundaries: this set will allows us to better understand the performance implications of technical decisions we make wrt. schema building.
This set, unlike others, does not declare any query: we are, for now, only interested in the schema building, which is tested with an ad-hoc script.
## Remaining work
There are several points worth discussing, wrt. this PR:
- should we make the schema larger, to make measures more consistent?
- should we extend this idea of measuring schema build performance to other sets?
- how do we extend the report to include this new information?
