    make incomplete_consumer_project_id a valid UUID
    
    Unfortunately, when I added the CONF.incomplete_consumer_project_id and
    CONF.incomplete_consumer_user_id options, the default value for those
    options was an invalid UUID (it had 13 zeroes for the last part of the
    UUID instead of 12). This is preventing some work that tries to disable
    warnings about invalid UUIDs being stored in ovo UUIDField objects.
    
    The work to "heal allocations" will be able to fix up any deployments
    that deployed the invalid UUID default CONF value because it looks for
    any instances in Nova where the placement allocation records don't have
    a matching user/project and replaces the mismatched user/project IDs on
    the consumer appropriately.

Title:
  The default of the missing project_id and user_id in placement is an
  invalid UUID

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  The placement config incomplete_consumer_project_id and
  incomplete_consumer_user_id defaulted to an invalid UUID[1]:

  DEFAULT_CONSUMER_MISSING_ID = '00000000-0000-0000-0000-0000000000000'

  Hint, the last block has 13 digits instead of 12. The DB schema
  doesn't catch this as it stores UUIDs in integer fields[2].
