Enforce unique instance uuid in data model
The instances.uuid column in the data model is not unique but by definition a UUID should be unique, and given how it's used within nova and across other openstack services like glance, neutron, ceilometer, etc, it should be unique. Furthermore, there are Foreign Keys created against instances.uuid so it should be unique (this is a requirement for DB2 support and blueprint db2-database).
The instances.uuid field is enforced to be unique at the nova objects layer today (see nova.objects.
The related nova-spec provides the detailed information on the blueprint design.
