Stable Compute Node UUIDs
Nova has long had a dependency on an unchanging hostname on the
compute nodes. This spec aims to address this limitation, at least
from the perspective of being able to detect an accidental change and
avoiding catastrophe in the database that can currently result from a
hostname change, whether intentional or not.
