Previously, the fake RESTClient in client-go required a Registry. It used the Registry to fetch the GroupVersion for the fake client. However, the way it did so was dubious in some cases (it hard-coded the default API group in places), and not strictly necssary. This updates the fake client to just recieve the GroupVersion and internal group name directly, instead of requiring a Registry, so that it can be consumed in unit tests where a Registry isn't necessarily readily available (e.g. elsewhere in client-go).
