Previously the role assumed that all deployers wanted all queues to be HA. Performance testing by Mirantis and Intel has suggested that throughput increases can be dramatic when disabling HA queues, see: http://docs.openstack.org/developer/performance-docs/test_results/mq/rabbitmq/index.html Therefore, we should allow deployers to set their own policies when desired.
