In certain cases, GitLab can miss a PostReceive invocation the first
time a branch is pushed. When this happens, the "branch created" hooks
are not run, which means various features don't work until the branch
is deleted and pushed again.

This MR changes the `Git::BranchPushService` so it checks the cache of
existing branches in addition to the `oldrev` reported for the branch.
If the branch name isn't in the cache, chances are we haven't run the
service yet (it's what refreshes the cache), so we can go ahead and
run it, even through `oldrev` is set.

If the cache has been cleared by some other means in the meantime, then
we'll still fail to run the hooks when we should. Fixing that in the
general case is a larger problem, and we'd need to devote significant
engineering effort to it.

There's a chance that we'll run the relevant hooks *multiple times*
with this change, if there's a race between the branch being created,
and the `PostReceive` worker being run multiple times, but this can
already happen, since Sidekiq is "at-least-once" execution of jobs. So,
this should be safe.

The feature flag has been introduced an was turned off by default,
now the it will default to be turned on. That change would still allow
users to turn this feature off by leveraging the Rails console by
running:

`Feature.disable("gitaly_catfile-cache")`

Another option is to manage the number of items the LRU cache will
contain, by updating the `config.toml` for Gitaly. This would be the
`catfile_cache_size`:

Fix header alignment on wiki and kubernetes pages

Closes #63231

The GitalyClient held a lot of logic which was all very tightly coupled.
In this instance the feature logic was extracted to make it do just a
little less and create a bit more focus in the GitalyClient's
responsibilies.
