Tried to reproduce issue with

1. Find "primary controller":
root@node-2:~# ifconfig | grep br-ex-hapr
br-ex-hapr Link encap:Ethernet HWaddr 06:7a:c8:57:99:3b
2. Shutdown primary controller:
shutdown now -P
3. Wait 10 minutes
4. Run Heat OSTF tests

Observed Result:
Issue not reproduced with parameter "rabbit_ha_queues=True" in /etc/heat/heat.conf, so, it is a way to fix the issue, I will commit fix soon.
