Title:
  Nova delete instance fails if cleaning is not async

Status in Ironic:
  Expired
Status in OpenStack Compute (nova):
  Invalid

Bug description:
  When node cleaning is not async (conductor starts cleaning immediately
  in do_node_tear_down()) Nova delete instance fails. Nova tries to
  update Ironic port (remove vif id), but conductor releases a lock only
  after thread with cleaning completed. Because cleaning usually is not
  a short time action Nova fails after retries. This bug can affects any
  out-of-tree driver, reproduced on Ansible deploy driver PoC (
  https://review.openstack.org/#/c/238183/ ).
