Create new mixmatch project

Proxy service to enable accessing resources (images, volumes, snapshots)
across federated deployments.

The proxy replaces the cinder and glance endpoint in the service catalog,
and forwards API calls to the correct OpenStack deployment based on
object UUID.

This allows Nova to be able to attach volumes in a federated OpenStack,
among other things.
