Hi,

In kolla-ansible yoga environment, rabbitmq queues are set to quorum by default instead of classical mirroring, as it seems they are not replicated (per queue has +0 quorum). 

We tried to find a solution to handle it in configs, but we couldn't find it and we set queues to be replicated by using CLI commands (rabbitmq-queues grow). 

Now, my questions are:
1- Why do all rabbitmq queues come as non-replicated by default?
2- How can we set HA mode to quorum queues?
