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`:
https://gitlab.com/gitlab-org/gitaly/blob/0dcb5c579e63754f557aef91a4fa7a00e5b8b127/config.toml.example#L27

Closes: https://gitlab.com/gitlab-org/gitaly/issues/1712

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.

Introduce default: for gitlab-ci.yml

Closes #62732

See merge request gitlab-org/gitlab-ce!24627

This moves all existing `image/services/before_script/variables`
into `default:`. This allows us to easily add a default and
top-level entries. `default`: is keep backward compatible: to
be considered to be job if `default:script:` is specified. This
behavior should be removed.

All existing `image/services/before_script/variables` are properly
handled in root context.

We are deprecating this service in favor of instance wide clusters.

we finally completelly remove KubernetesService.
