## Description
This PR iterates on #459.
Rather than serving the engine metadata it serves an arbitrary file,
given by the command line argument `--introspection-metadata`.
Specifying this argument gives rise to endpoints `/metadata` and
`/metadata-hash`.
Update: We only load the file in at engine startup and serve that
version. Changing the file on disk will not change what the engine
serves.

## Description
Previously we moved all our types around in one big bucket, meaning we
often had to check we had the thing we wanted, this splits it up so
dependencies are more granular and clearer.
This means instead of passing `types` around, we'll have both
`scalar_types` or `object_types`. Usually just `object_types` though.

## Description
As a temporary means of supporting a local development setup, this PR
adds a `/metadata` endpoint that serves the raw metadata that the engine
was started with.

This injects trace context headers into requests to the auth hook,
allowing us to figure out how much time is spent here.
I added a basic tracing setup to the dev-auth-webhook, using
`tracing-util`, allowing me to verify that this works. This required
moving the Dockerfile to the root so the context contains the
`tracing-util` crate too.
I have also fixed the reference agent (by updating it), and patched our
Docker Compose files to correctly set up connectivity to Jaeger.

I needed this, so I made it. It's nothing too complex: we just
pretty-print the `schemars` schema for the root `Metadata` type.

## Description
Following the approach taken here:
https://github.com/hasura/ndc-postgres/pull/402
This moves the `clippy` settings into the Cargo workspace file instead
of passing them for each invocation.
We enable all pedantic settings, run `cargo clippy --fix` to auto fix a
few things, and then manually disable all other lints.
Plenty of them are worth enabling and fixing in future IMO.

- Introduce a field in NDC `Configuration` struct that carries an
optional limit (`usize`) value.
- When set, reject NDC response that is greater than the limit.
- Define a `HttpContext` struct that captures both `reqwest::Client` and
an optional limit value. Replace the `http_client` argument with
`http_context: &HttpContext` in all execute related functions.
- The `execute_query` function caller in multitenant code need to pass a
reference to `HttpContext` with appropriate NDC response size limit.

## Description
We'll shortly be adding `BooleanExpression` to `ValueExpression`, which
will require resolving the internal `ModelPredicate`. This PR adds a
resolving step for `ValueExpression` to simplify that later step. It is
essentially a no-op to introduce a new type.

This seems appropriate now that we've stabilized the new configuration.
Of note are the configuration updates and the use of an environment
variable to specify the connection URI. This upgrade also fixes the
health checks.
Regenerating the configuration lost the table descriptions, which seems
to be because they were not present in the Chinook SQL. I have dragged
the Chinook SQL in from ndc-postgres and kept it separate from the
initialization of other tables.
The auto-generated configuration is slightly different from the
manually-created configuration in that the collection names are
singular, not plural. This means that I had to change a lot of test
metadata files too.

…arger ones
…the goal being to save on data transfer costs, libdeflate being much faster than zlib for larger inputs and at higher compression levels. A few notes:
In last month...
- 95% of response bodies > 20kB compress below 32% (with zlib level 1)
- The 10% of responses > 20kB comprise 75% egress traffic to clients
- libdeflate at level 6 is comparable in performance to zlib level 1, and twice as fast as zlib level 6
- We expect compressing 20kB+ response bodies at level 6 to reduce data transfer to clients by 25% or so (although this is difficult to predict accurately)
The new libdeflate bindings used here also need review: https://github.com/hasura/libdeflate-hs

This fixes the poor memory behavior we observe in #9447. Observe a
haskell program has layers of memory usage/management, from inner to
outer:
1) objects on the haskell heap aka "live data"
2) blocks of memory managed by the haskell RTS, containing live data
(and including overheads from fragmentation and space for
copying-into during GC)
3) foreign data malloc'd and free'd from haskell, but indirectly (during
GC, "finalizers" are run that call `free` generally)
4) the implementation of malloc itself we're linked against maintains a
list of blocks of free memory requested from the OS; it decides when
to return blocks back (reflected in lower RSS from top), and
fragmentation is also a concern here
4a) should the malloc decide to return memory, it might use MADV_FREE
or another mechanism which won't be reflected in RSS unless there is
memory pressure. This further complicates things
(1) and (2) can be monitored from /dev/rts_stats . (3) can be monitored
with heaptrack, valgrind, etc. (4) was where our issues were here.
mimalloc helps because:
- it seems to handle fragmentation better, for the large response sizes
in our reproo
- it is more eager to return memory back to the OS (but note: newer
versions use MADV_FREE and probably aren't useable for us. See:
https://github.com/microsoft/mimalloc/issues/776 )
note that `static.o` gets linked second, but according to my tests the
order shouldn't matter (despite what mimalloc docs suggest):
```
gcc '-fuse-ld=lld' -Wl,--no-as-needed -o
/home/me/Work/hasura/graphql-engine-mono/dist-newstyle/build/x86_64-linux/ghc-9.4.5/graphql-engine-1.0.0/x/graphql-engine/opt/build/graphql-engine/graphql-engine

```
NOTE: the promptness of memory reclamation depends on both
HASURA_GRAPHQL_PG_TIMEOUT and HASURA_GRAPHQL_PG_CONN_LIFETIME. By
default a connection's resources will be GC'd after 3min when idle, or
after no more than 10 minutes.

Previously when users had an idle system with a large working set (i.e. large schema) they would likely see CPU spikes every 10 seconds.
See: https://github.com/hasura/graphql-engine/issues/9592#issuecomment-1580543694
Now we perform a lighter-weight minor GC in that case.

context: This is foundation work, before we change how the server chooses to compress or not
part of effort: #5518
-----
Prior to this change it was difficult to understand how the functionality in this module related to the semantics of Accept-Encoding. We also didn't correctly handle directives with qvalues.
After this change certain technical infelicities are called out without modifying the behavior of the server; for instance we continue to fall back to identity (no compression) in the case where technically we're supposed to return 406, and we also continue to treat `*` conservatively as meaning “use no compression”.
The only external change here is `gzip;q=x.y` now results in a zipped response.

This increases compile times for full build of exe:graphql-engine from
13min to 16min on my machine, less on CI.
NOTE: O1 on its own improves compile time slightly (~80 sec) and doesn't
negatively impact performance at all, seemingly:

Just forcing some of the most numerous thunks (with -hi profiling), it
seems some of these were retaining significant amount of data

This improves memory residency, at least before queries arrive.
Compile time and binary size seem about the same.
In starting to look at a dominator tree of the heap loading chinook, I
saw a chain of alternating function/InputFieldsParser closures from
updateOperator, and I was curious what would happen if I inlined some of
the continuation-passing -like schema parser functions. It looks like it
forces some function closure thunks, but I don't have more insight than
that.
