Code review comment for lp://qastaging/~corey.bryant/charms/trusty/nova-compute/amulet-novacc

The git amulet tests only deploy the current charm from source, and the other charms are deployed from packages. This has worked ok so far except nova-compute started getting some odd instance creation timeouts due to what looked like oslo.messaging issues. Deploying nova-cc from source in addition to nova-compute from source seems to fix it.
