-1, I think Monty stated this well

"Honestly, I think we should ditch it. Glance is our image service, not
nova, we should use it. For user-experience stuff,
python-openstackclient should be an excellent way to expose both through
a single tool without needing to proxy one service through another."

We don't want nova to be the proxy for all other services, that
partially defeats the purpose of splitting them off.   We have better ways
of making everything look like a single API, such as:

* better python-openstackclient
* Make sure all services can run as one endpoint, on the same port.  So a
REST call to $IP/images/ would go to glance and a call to $IP/instances
would go to nova
