Open Stack

Hi Steve,

There was a long thread about dropping project ID/tenant ID from the URL at
http://openstack.markmail.org/thread/c2wi2uwdsye32z7f

Looking back through it, it looks like nova v3 has it removed
https://blueprints.launchpad.net/nova/+spec/v3-api-remove-project-id

Maybe something in there will lend itself to reuse in heat.
