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. Change-Id: Icab0b783e2233cad9a93c04758a5bccac0832203
