openstack overcloud plan delete can get stuck forever

[Michele Baldessari]

If the stack delete failed:
| 8ac16fe9-a8bc-4aba-99c6-f6244731af08 | overcloud | 4eb73f99e4ac4e9a9b904687023d2b3c | DELETE_FAILED | 2018-06-15T05:09:54Z | 2018-06-15T07:55:00Z |

It seems that the 'openstack overcloud plan delete' command can stay stuck forever.
(undercloud) [stack@undercloud ~]$ openstack overcloud delete --yes overcloud
Deleting stack overcloud...
Started Mistral Workflow tripleo.stack.v1.delete_stack. Execution ID: d8f03440-1e5b-4000-a6a1-6a4d54e808c7
Waiting for messages on queue 'tripleo' with no timeout.
.... hangs forever....

It should detect that the stack deletion failed and return an error or somehow display what it is trying to do as it is a bit confusing for an operator.

    Exit wait_for_stack_does_not_exist if the status is delete failed

    The current implementation waits for 10 minutes, regardless of the stack
    status. This will exit earlier and fail the workflow, triggering the
    error handling in the delete_stack workflow.
