We've removed the external ingress for the Container Registry.  This
allows us to utilize our existing cookbook and attributes to configure a
new server.  This makes the GKE specif items obsolete.  This should be
removed anyways as a small bug prevents us from being able to flip
between the GKE backend and our VM backend cleanly.
