* Update openstack-ansible-rabbitmq_server from branch 'master'
  to f5ecdf4852b66af63e2fb68aa0c867164964eda4
  - Adjust legacy OpenStack HA policy to make reply queues HA
    
    Changes in oslo.messaging for 2023.1 exposed a known race
    condition in RabbitMQ when dealing with non-HA classic queues.
    When a RMQ cluster member is taken down, clients failing over
    to other members may erroneously be told a queue exists when it
    is in the process of being deleted. This can cause them to
    permanently sit waiting for messages from a queue that no longer
    exists until their services are restarted.
    
    Making the reply queues HA resolves this issue, at the expense
    of a x3 increase in reply queues across the cluster. My
    assumption is that reply queues were previously excluded from HA
    policy as a performance gain given their link to the number of
    compute nodes in an OpenStack deployment.
