om_enable_rabbitmq_high_availability is True but no mirroring policy has been found.
Currently the procedure to migrate from transient non-mirrored queues to durable mirrored queues is manual.
Please follow the process described here: https://docs.openstack.org/kolla-ansible/latest/reference/message-queues/rabbitmq.html#high-availability.
Note that this process may take several hours on larger systems, and may cause a degredation in performance at large scale.
If you do not wish to enable this feature, set om_enable_rabbitmq_high_availability to False.

- container_facts['rabbitmq'] is defined
- om_enable_rabbitmq_high_availability | bool
