Title:
  Ironic: "nova delete" doesn't work when instance is spawning

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  The "nova delete" command can be issued while the instance is spawning
  and even Ironic support aborting a deployment mid-operation (when node
  is in WAITDEPLOY state).

  But if you issue a "nova delete" while the instance is spawming with
  the Ironic driver the instance will be stuck there and nothing will
  happen. That's because of a lock[1], basically the Ironic driver won't
  return from spawn() until the node have been successfully deployed or
  error out and that's holding the lock.

  WORKAROUND:

  As a work around, you can issue "nova delete" to the instance and that
  will mark the task_state as "deleting". And then you can delete the
  instance directly via the Ironic API as well by doing:

  $ ironic node-set-provision-state <node uuid> deleted

  That will realease the instance.
