probably, the reason of failure is difference between rabbitmq's versions on added controller node and existing controllres

root@node-5:~# dpkg -l | grep rabbit
ii rabbitmq-server 3.6.6-1~u14.04+mos2 all Multi-protocol messaging broker

root@node-1:~# dpkg -l | grep rabbit
ii fuel-rabbit-fence 9.0.0-1~u14.04+mos8607 all Fuel RabbitMQ fencing utilitites
ii rabbitmq-server 3.6.5-1~u14.04+mos1 all AMQP server written in Erlang

we need to make a conclusion: rewrite or delete the corresponding test.
