Allow forcing nova compute_id

Browse Source 
Developers that need to stack and re-stack non-AIO compute-only
environments will want to be able to keep the compute node uuid the
same across runs. This mimics the behavior of a deployment tool that
pre-creates the uuids, so it matches pretty well. Default to the
current behavior of create-on-start, but allow forcing it ahead of
time to something specific.

# Allow forcing the stable compute uuid to something specific. This would be

# stay the same each time is what developers want. Set to a uuid here or
