## Problem
Previously, the background worker that collects the list of installed
extensions across DBs had a timeout set to 1 hour. This cause a problem
with computes that had a `suspend_timeout` > 1 hour as this collection
was treated as activity, preventing compute shutdown.
Issue: https://github.com/neondatabase/cloud/issues/30147
## Summary of changes
Passing the `suspend_timeout` as part of the `ComputeSpec` so that any
updates to this are taken into account by the background worker and
updates its collection interval.
This check API only cheks the safekeeper_connstrings at the moment, and
the validation is limited to checking we have at least one entry in
there, and no duplicates.
## Problem
If the compute_ctl service is started with an empty list of safekeepers,
then hard-to-debug errors may happen at runtime, where it would be much
easier to catch them early.
## Summary of changes
Add an entry point in the compute_ctl API to validate the configuration
for safekeeper_connstrings.

This is in preparation of using compute_ctl to launch postgres nodes
in the neon_local control plane. And seems like a good idea to
separate the public interfaces anyway.
One non-mechanical change here is that the 'metrics' field is moved
under the Mutex, instead of using atomics. We were not using atomics
for performance but for convenience here, and it seems more clear to
not use atomics in the model for the HTTP response type.
Including, but not limited to:
* Fixes to neon management code to support walproposer-as-an-extension
* Fix issue in expected output of pg settings serialization.
* Show the logs of a failed --sync-safekeepers process in CI
* Add compat layer for renamed GUCs in postgres.conf
* Update vendor/postgres to the latest origin/main
Currently it's included with minimal changes and lives aside of the main
workspace. Later we may re-use and combine common parts with zenith
control_plane.
This change is mostly needed to unify cloud deployment pipeline:
1.1. build compute-tools image
1.2. build compute-node image based on the freshly built compute-tools
2. build zenith image
So we can roll new compute image and new storage required by it to
operate properly. Also it becomes easier to test console against some
specific version of compute-node/-tools.
