This removes the ability to pass in a different version. We can instead
create a new entry in the SUPPORTED_API_GROUPS hash for a different
version if need be.

Build using `define_method` directly from the constant, saves us writing
api_groups strings twice.

Essentially make #build_kubeclient do less.

Should be much clearer now

KubeClient no longer needs the list of api_groups to be passed in - all
groups will be supported.

As the default for `#get_deployments` will be `v1beta1` (see
KubeClient#extensions_client), we can rely entirely on #kubeclient
instead of calling #build_kube_client!

Find and replace everywhere we pass in `api_groups` to KubeClient, as no
longer needed

We should have access to #core_client, #rbac_client,
and #extensions_client without having to pass in an awkward array.

Also change api_version to default_api_version, which allows us to use a
different version for an individual client. Special case for
apis/extensions which only goes up to v1beta1.

Makes #hashed_client private

Removes the #clients and #discover! methods which are un-used

EE: Move Project#rename_repo to a service class

See merge request gitlab-org/gitlab-ee!8028

This moves the logic of Project#rename_repo and all methods _only_ used
by this method into a new service class: Projects::AfterRenameService.
By moving this code into a separate service class we can more easily
refactor it, and we also get rid of some RuboCop "disable" statements
automatically.

During the refactoring of this code, I removed most of the explicit
logging using Gitlab::AppLogger. The data that was logged would not be
useful when debugging renaming issues, as it does not add any value on
top of data provided by users.

I also removed a variety of comments that either mentioned something the
code does in literal form, or contained various grammatical errors.
Instead we now resort to more clearly named methods, removing the need
for code comments.

This method was chosen based on analysis in
https://gitlab.com/gitlab-org/release/framework/issues/28. In this issue
we determined this method has seen a total of 293 lines being changed in
it. We also noticed that RuboCop determined the ABC size
(https://www.softwarerenovation.com/ABCMetric.pdf) was too great.

[QA] Move epic-related method to EE class

This model will be used to persist into database Kubernetes properties,
such as namespace, service account name and service account token.
