so that we can use API::Internal namespace.

This commit removes one RuboCop offense from its todo file.

`Array.reverse_each` is faster than `Array.reverse.each` because:

* reverse.each creates a new array then loops each element
* reverse_each loops in reverse order (no intermediate array created)

When used with a Hash, `.keys.include?` is bad because:

1. It performs a O(n) search instead of the efficient `.has_key?`
2. It clones all keys into separate array.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/64975

Now that KubernetesService can no longer be a DeploymentPlatform we can
remove all kubernetes client code and KubernetesService edge cases.

We are deprecating this service in favor of instance wide clusters.
Therefore we removed some code that is not anymore needed for a
readonly cluster and also we added some flags to allow for this
deprecation. These flags are to be removed in the next release when
we finally completelly remove KubernetesService.

This adds Ruby 2.6 support.

This reverts commit a5378665.

Cleanup code, and refactor tests that still use Rugged. After this, there should
be no Rugged code that access the instance's repositories on non-test
environments. There is still some rugged code for other tasks like the
repository import task, but since it doesn't access any repository storage path
it can stay.
