Summary: When a port is deleted out of band (while still attached to an
instance), any associated QoS bandwidth resources are orphaned in placement.

Consensus:
- Neutron to block deleting a port whose "owner" field is set.
- If you really want to do this, null the "owner" field first.
- Nova still needs a way to delete the port during destroy. To be
discussed. Possibilities:
  - Nova can null the "owner" field first.
  - The operation can be permitted with a certain policy role, which
Nova would have to be granted.
  - Other?
