Add docker RABL to API

Without this template, compute_resources/main.json.rabl will look for a
docker.json template with no avail. This results in failed
api/compute_resources index and show calls (for Docker CRs).

ENTRYPOINT and CMD might be nil on the container. In this case, the
current code just throws a 500 because it's checking for .any? on a nil
object instead of .present?
