Run repository checks parallel for each shard

Closes #48042

See merge request gitlab-org/gitlab-ce!20179

There is only 1 `HEALTHY_SHARD_CHECKS` used:
Gitlab::HealthChecks::GitalyCheck

So we can simplify code to get the list of healthy shard names.

The RepositoryCheck::DispatchWorker will start a
RepositoryCheck::BatchWorker for each healthy shard.

Closes gitlab-org/gitlab-ce#48042

It already existed in EE in the Geo namespace. This change brings it
to CE.

Improve Hashed Storage documentation for rollback

See merge request gitlab-org/gitlab-ce!20203

We should mark the MR as merged as first thing on PostMergeService as in practice it is already merged on the repository. Happens that errors may happen when executing external services such as Issues::CloseService, and we do not want a MR hanging as opened because of that.

Resolve "Search dropdown hides & shows when typing"

Closes #48461

See merge request gitlab-org/gitlab-ce!20187

Prior to this change, health checks checked for writeability of the NFS
shards. Given we're moving away from that, this patch extends the checks
for Gitaly to check for read and writeability.

Potentially some dashboards will break, as over time these metrics will
no longer appear as Prometheus doesn't get the data anymore.
Observability in the circuit breaker will be reduced, but its not
expected to be turned on and the circuit breaker is being removed soon
too.
