Get Pebbles to be able to deploy Nova and spin up vms. [4/6]

These pull request updates allow Nova and all its prerequisites to
deploy using their default proposals, and test that Nova is able to
spin up a VM.

We still need to have proper smoketests for Quantum and Cinder, and
the Nova smoketests need to include testing attaching and detaching
networks and volumes to vms.
