This improves the behavior of health-checks
introducing two levels of them:

- service level: checks served by `sidekiq|web_exporter:'
  served on separate port

- application level: checks served by `/-/metrics` endpoint
  of `HealthController`

The changes makes the:

- `/liveness` always indicate that application is ready
  and not deadlocked
- `/readiness` to indicate:

The changes for `/readiness`:

- on service level: the status of the service if it can accept
  and process connections

- on application level: the status of external components if they
  are accessible

The `on service level` and `on application level` do not share
any checks, they have different checks exposed.

Add blackout period support for `web_exporter:`

See merge request gitlab-org/gitlab!17962

This introduces `#run_thread` method.

The `#start_working` is executed in lock context,
the same as `#stop_working`. This allows safe
initialisation of resources before `#run_thread`
consumes them.

Due to a race condition during sidekiq process start-up, we might end
up losing prometheus db files due to doing a cleanup after first
creating them. By re-initializing after every cleanup, we side-step
the issue, but it's not really a clean solution.
