Multinode with HA with 3 controllers

Steps to reproduce

1) find primary controller (crm status)
2) On the other two controllers start

watch "rabbitmqctl eval 'rabbit_misc:which_applications().' |grep rabbit,"

to see whats happening with RabbitMQ cluster and rabbit application. You should see the line

{rabbit,"RabbitMQ","3.3.5"},

3) Turn off the primary controller and see whats happening with other two controllers

Because of currrent HA implementation you will see that rabbitmqctl could not connect to the node
something like that
Error: unable to connect to node 'rabbit@node-10': nodedown
or
line with rabbitmq application could disappear

The normal behaviour I believe should be
No disconnection on two others controllers and no full cluster failover when primary controller goes down

Also in the
https://bugs.launchpad.net/fuel/+bug/1435250
noted
3) destroy the master, node-3
Expected: new master election, failover with full downtime - no nodes can process AMQP connections

I think It should be improved
