More fine-grained metrics for sidekiq workers

Closes #32258

See merge request gitlab-org/gitlab!18817

We currently only measure the global (node-level) business in terms
of jobs being processed. We would instead like to be able to know
for each sidekiq process how saturated it is in terms of actual
concurrency vs requested/max concurrency.

This patch does the following:

- add a worker/process dimension to all existing metrics
- introduce a new metric to observe concurrency per process

by relating "actual job count per process" to "max job count per
process" we can then obtain some sort of saturation metric.

Change url for tag push events in chat message integration

See merge request gitlab-org/gitlab!18126

Instead of the branch_url being set to `/commits/<ref>` for both tags
and regular pushes, branch_url is conditionally set to `/-/tags/<ref>`
for tags.

Improve pod logs API

See merge request gitlab-org/gitlab!17881

- The rollout_status is required to get pod_names, so return nil, which
will cause the controller to return 202 or 204.
- Return additional parameters like pods, pod_name, container_name.
- pods is the names of all pods of this environment.
- Return error when no pods are available.
- pod_name is the name of the pod whose logs are being returned.
- container_name is the name of the container within the pod whose logs
are being returned. container_name can be nil when the request to k8s
API was made without a container_name.

Make documentation linter show target path

See merge request gitlab-org/gitlab!18895

- We are seeing flaky documentation lint checks that do not always catch
  when a file inside the documentation is set with the executable bit.
  The check to find executable documents runs inside a subshell and its
  error output is not being redirected, nor would it count those errors
  when running `wc -l`. It seems implausible that we are failing to `cd`
  into the correct directory, but this is the one method I know of that
  would cause the `find` expression to fail silently in the logs. It is
  also just useful to see that yes, we are running the documentation
  linter against a reasonable directory in the logs.

Re-raise exception if there is no response

Closes #34332

See merge request gitlab-org/gitlab!18856

It's possible that `rescue ExceptionWithResponse` could catch a
type of exception that has no response. So we need to check if there
is a response before we return it

Allow Gitaly to work without a PG connection

Closes #34205

See merge request gitlab-org/gitlab!18659

Gitaly didn't require a PG connection to connect to, though recently we
started to pass feature flags to Gitaly in different manners. That
change would now require a PG to be running. This is not ideal,
especially if only for feature flags.

This change rescues a bad connection error, and breaks the required
dependency between PG and Gitaly.

Fix confusion in background verification doc

This call is currently only used by `UpdateRepositoryStorageService`,
and it can easily time out after 30 seconds for large projects. Increase
it to a long timeout to ensure this doesn't fail prematurely.
