This should be closed out now that auto-created consumers are deleted
and consumers with no allocations are auto-deleted.

Title:
  Consumers never get deleted

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  We don't have an API to delete a consumer.  It gets created implicitly
  when allocations are created against it, but it doesn't get deleted
  when the consumer's last allocation is removed.  In some uses of
  placement, such as nova's, there is a high rate of turnover of
  consumers (instances, in nova) so this leakage has the potential to be
  problematic.

  (Note that we have the same issue for aggregates, but don't currently
  have a known use case with a lot of aggregate turnover, so it is less
  likely to be a problem soon.)

  Possible solutions:
  - Delete a consumer record automatically when its last allocation goes away.  This is nice and symmetrical, but a behavior change for the guy *recreating* a consumer (today he has to use the current generation; with this change he would have to use ``null``).
  - Provide an operation for deleting consumers.  This is an extra step for callers (which is okay).  But do we also provide an explicit (redundant) operation for creating them, just for the sake of symmetry?
  - Your idea here.
