1. Adds local-proxy to compute image and vm spec
2. Updates local-proxy config processing, writing PID to a file eagerly
3. Updates compute-ctl to understand local proxy compute spec and to
send SIGHUP to local-proxy over that pid.

Follow-up of #9234 to give hyper 1.0 the version-free name, and the
legacy version of hyper the one with the version number inside. As we
move away from hyper 0.14, we can remove the `hyper0` name piece by
piece.
Part of #9255

Microsoft exposes JWKs without the alg header. It's only included on the
tokens. Not a problem.
Also noticed that wrt the `typ` header:
> It will typically not be used by applications when it is already known
that the object is a JWT. This parameter is ignored by JWT
implementations; any processing of this parameter is performed by the
JWT application.
Since we know we are expecting JWTs only, I've followed the guidance and
removed the validation.
* tracing-utils now returns a `Layer` impl. Removes the need for crates
to
import OTel crates.
* Drop the /v1/traces URI check. Verified that the code does the right
thing.
* Leave a TODO to hook in an error handler for OTel to log errors to
when it
assumes the regular pipeline cannot be used/is broken.
misc changes split out from #8855
- **allow cloning the request context in a read-only fashion for
background tasks**
- **propagate endpoint and request context through the jwk cache**
- **only allow password based auth for md5 during testing**
- **remove auth info from conn info**
PR #7782 set the dependency in Cargo.toml to 'master', and locked the
version to commit that contained a specific fix, because we needed the
fix before it was included in a versioned release. The fix was later
included in parquet crate version 52.0.0, so we can now switch back to
using a released version. The latest release is 53.0.0, switch straight
to that.

Addresses the 1.82 beta clippy lint `too_long_first_doc_paragraph` by
adding newlines to the first sentence if it is short enough, and making
a short first sentence if there is the need.
In #8863 I replaced the threadpool with tokio tasks, but there was a
behaviour I missed regarding cancellation. Adding the JoinHandle wrapper
that triggers abort on drop should fix this.
Another change, any panics that occur in password hashing will be
propagated through the resume_unwind functionality.
Some tests were very slow and some tests occasionally stalled. This PR
improves some test performance and replaces the custom threadpool in
order to fix the stalling of tests.
In proxy I switched to a leaky-bucket impl using the GCRA algorithm. I
figured I could share the code with pageserver and remove the
leaky_bucket crate dependency with some very basic tokio timers and
queues for fairness.
The underlying algorithm should be fairly clear how it works from the
comments I have left in the code.

In benchmarking pageserver, @problame found that the new implementation
fixes a getpage throughput discontinuity in pageserver under the
`pagebench get-page-latest-lsn` benchmark with the clickbench dataset
(`test_perf_olap.py`).
The discontinuity is that for any of `--num-clients={2,3,4}`, getpage
throughput remains 10k.
With `--num-clients=5` and greater, getpage throughput then jumps to the
configured 20k rate limit.
With the changes in this PR, the discontinuity is gone, and we scale
throughput linearly to `--num-clients` until the configured rate limit.

Add binary for local-proxy that uses the local auth backend. Runs only
the http serverless driver support and offers config reload based on a
config file and SIGHUP
## Problem
#8736 is getting too big. splitting off some simple changes here
## Summary of changes
Local proxy wont always be using tls, so make it optional. Local proxy
wont be using ws for now, so make it optional. Remove a dead config var.
basic JWT implementation that caches JWKs and verifies signatures.
this code is currently not reachable from proxy, I just wanted to get
something merged in.
This reverts #8076 - which was already reverted from the release branch
since forever (it would have been a breaking change to release for all
users who currently set TimeZone options). It's causing conflicts now so
we should revert it here as well.
## Problem
1. Hard to correlate startup parameters with the endpoint that provided
them.
2. Some configurations are not needed in the `ProxyConfig` struct.
## Summary of changes
Because of some borrow checker fun, I needed to switch to an
interior-mutability implementation of our `RequestMonitoring` context
system. Using https://docs.rs/try-lock/latest/try_lock/ as a cheap lock
for such a use-case (needed to be thread safe).
Removed the lock of each startup message, instead just logging only the
startup params in a successful handshake.
Also removed from values from `ProxyConfig` and kept as arguments.
(needed for local-proxy config)
## Problem
The current bucket based rate limiter is not very intuitive and has some
bad failure cases.
## Summary of changes
Switches from fixed interval buckets to leaky bucket impl. A single
bucket per endpoint,
drains over time. Drains by checking the time since the last check, and
draining tokens en-masse. Garbage collection works similar to before, it
drains a shard (1/64th of the set) every 2048 checks, and it only
removes buckets that are empty.
To be compatible with the existing config, I've faffed to make it take
the min and the max rps of each as the sustained rps and the max bucket
size which should be roughly equivalent.
## Problem
On Azure we need to use username-password authentication in proxy for
regional redis client.
## Summary of changes
This adds `redis_auth_type` to the config with default value of "irsa".
Not specifying it will enforce the `regional_redis_client` to be
configured with IRSA redis (as it's done now).
If "plain" is specified, then the regional client is condifigured with
`redis_notifications`, consuming username:password auth from URI. We
plan to do that for the Azure cloud.
Configuring `regional_redis_client` is required now, there is no opt-out
from configuring it.

PR #8299 has switched the storage scrubber to use
`DefaultCredentialsChain`. Now we do this for `remote_storage`, as it
allows us to use `remote_storage` from inside kubernetes. Most of the
diff is due to `GenericRemoteStorage::from_config` becoming `async fn`.
