Remove Rancher Credential Provider from upstream kubernetes

This is useful only in rancher environment, they are using this in a
very old branch (1.6), they are currently at 2.2.x. There is just no
point in us carrying this code as this is not useful to anyone else
outside of the rancher environment. Let us please remove this code from
upstream.
