Upgrade auto-update to 0.2.7 which contains a fix to a bug causing some threads not seeing updates to the cached values.
(cherry picked from commit a2a592a617)
`AppState.hs` is imported by many modules. Some of those modules contain
important functions that need to be imported back to `AppState.hs`, causing
circular dependency problem.

`postgrest-build` now builds twice as fast as compared to previous
build time. This can be tested by running `rm -rf dist-newstyle/` and
then run `postgrest-build`.

src/ now contains all source code - in subdirectories, according to the
.cabal component they belong to. This will allow us to put vendored
libraries in the same place - and later split our own code into multiple
components/libraries as well.
Runs the doctests much faster, which is potentially useful in
combination with postgrest-watch for local development.
This implies that doctests run on compiled code, not in a GHCi session,
which has some implications:
- Only exported functions can be tested.
- Imports need to be made explicit in doctests themselves.
On the flipside, this would allow us to potentially include doctest
results in code coverage, I believe.
This change is a requirement to vendor hasql, which otherwise breaks the
existing doctests: hasql contains a .hsc file, which *needs* to be
compiled - not interpreted - to make the tests work.
BREAKING CHANGE
Breaks the string comparison operators implemented in #3813. Those can
be replaced with regex searches using JSON Path `search()` function.

Before 9.12.1 it was necessary to mark functions as INLINABLE or INLINE to make GHC consider cross-module specialization of polymorphic functions.
9.12 added a new -fexpose-overloaded-unfoldings flag that exposes optimized polymorphic functions in interface files. -fspecialise-aggressively then makes GHC apply aggresive specialization.
Right now metrics observation handler does not track database connections but updates a single Gauge based on HasqlPoolObs events. This is problematic because Hasql pool reports various connection events in multiple phases. The connection state machine is not simple and to precisely report the number of connections in various states, it is necessary to track their lifecycles.
This change adds a ConnTrack data structure and logic to track database connections lifecycles. At the moment it supports "connected" and "inUse" connection counts precisely. The "pgrst_db_pool_available" metric is implemented on top of ConnTrack instead of a simple Gauge.
This commit removes auth middleware for it hides
side effects and obscures logic. The auth operations
are now done in its own stage in the request-response
cycle.
It also removes the logging middleware because now
we instead use observation module to log the response.
Upgraded warp to 3.4.13 which fixed https://github.com/yesodweb/wai/issues/853
Changed interrupt handling so that instead of killing the main thread, listening sockets are closed which triggers warp graceful shutdown.
Jumping past GHC 9.6, 9.8 and 9.10 immediately, because these versions
do not successfully build the static binary with TemplateHaskell and
iserv-proxy, yet.

The current version is too old and it prevented using latest features
like common stanzas and visibility fields.

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

The `Error.hs` module is getting bloated. This moves types
to another module for better separation of concerns.

Moves the `negotiateContent` function to `Plan/Negotiate.hs`
module. This also adds comments to describe the current approach
we have for negotiation.
