Kubernetes-commit: b9d865a8185b62d83e9ff81b0e3499a26ac6960d
Add two new constructors for versioned and unversioned RESTClients.
These new constructors allow to pass an http.Client to the RESTClient,
taking precence over the transport Config parameters.
Add a new helper function to generate an http.Client from the RESTClient
Config object.
