Something's rotten in the state of Rabbit... any action taken by Kolla-Ansible for RabbitMQ fails:
```

fatal: [ctl00 -> {{ service_rabbitmq_delegate_host }}]: FAILED! => {"censored": "the output has been hidden due to the fact that 'no_log: true' was specified for this result", "changed": false}
```
while running `list_users` on the host returns:
```
docker exec -ti rabbitmq /usr/sbin/rabbitmqctl -q -n rabbit list_users
user	tags
openstack	[administrator]
```

Kolla-ansible cannot reconfigure RabbitMQ either:
```

```
leaving the cloud in a somewhat strange and very down state while the cluster reports up and not in maintenance/showing alarms:
