Bug Description

Andrew pointed out http://lists.openstack.org/pipermail/openstack-dev/2015-November/079214.html
that for A/A case, instances of a clone might work better if configured with ordered=false.

For Fuel rabbitmq clustering, that might give a boost to a cluster bootstrap time, including failover cases.
All instances would join/recover in parallel rather than one by one, which might be *much* longer.

Fuel configures the clone with ordered=false as well. Hence, invalid
