When trying to scale-up rabbitmq cluster from 1-replica to 3 replicas, the rabbitmq operator internally calls rabbitmq-queues in the running rabbitmq pods to rebablance master queues in the rabbitmq cluster.

This is currently failing because the rabbitmq container image that we consume doesn't have rabbitmq-queues in the PATH. The rabbimq operator signals a failed reconciliation and blocks further reconciliations:
