Some helpers are provided for introspecting metrics already (used in JWT cache tests). This change provides facilities to additionally validate emited Observation events.
A new Spec module is also implemented, adding basic tests of schema cache reloading - their main goal is to excercise the new infrastructure.
- Create separate test suite for observability tests
- Create wrapper script `postgrest-test-observability`
- Add to CI and `postgrest-check`
- Move JWT cache tests under observability tests

(cherry picked from commit 58efc2680e)
The `--ready` flag is a wrapper around the admin server
`/ready` request. This is done through using an http client
library in postgrest.

This splits off the transaction concerns into a MainTx module
It's just moving some functions inside the Query module to the MainTx module.
Some types names were also changed so they don't have the "Query" prefix, to avoid confusion.
Changes:
1. Refactoring and some cleanup of JWT handling code:
* Instead of caching AuthResult cache decoded claims (which signature was verified). Validating claims and determining role is done after cache lookup
* Cleaned up API so that usage of it is simplified: lookupJwtCache cache key >>= parseClaims configJwtAud time
* Handling of JwtCacheState initialization and updates of configuration is encapsulated in Auth.JwtCache module
2. Generic high performance (hopefully) scalable, dynamically resizeable cache implementation based on stm, stm-hamt and sieve algorithm. It also integrates with PostgREST measurements infrastructure providing usage stats (ie. hit ratio, evictions count)
The dependency on it was removed in #3608 already, but we forgot to
remove it from postgrest.cabal, which caused it to still be built.
We didn't realize because all references of it were stripped away by
dead code elimination anyway.
This change introduces a PostgREST.Auth.Jwt module containing JWT validation functions.
The reason to extract them from Auth is to enable JwtCache module to reuse them without introducing module dependency cycle.
The former depends on th-orphans which does not cross-compile well,
because of template haskell usage.
neat-interpolation is also much better maintained.
This also potentially helps with packaging for Debian/Ubuntu in #2273.
Contravariant.Extras uses Template Haskell, which is hard to
cross-compile. Reducing usage of Template Haskell with the ultimate goal
of solving all cross compilation challenges.
Update hasql-notifications to include the fix on
https://github.com/diogob/hasql-notifications/issues/24.
Which now reveals the following error:
```
$ postgrest-with-postgresql-16 --replica -f test/spec/fixtures/load.sql postgrest-run

```
This is still not good because the LISTEN channel will be retried
forever without a backoff.
