Comment 13 for bug 1539586

there is some places in this test where we do not use method get_rabbit_nodes , so we still has issue with parse output, like here
 def count_run_rabbit(node, all_up=False):
            with self.fuel_web.get_ssh_for_node(node.name) as remote:
                cmd = 'rabbitmqctl cluster_status'
                with RunLimit(seconds=60, error_message=error.format(cmd)):
                    out = run_on_remote(remote, cmd=cmd, raise_on_assert=False)
            run_nodes = [el for el in out if 'running_nodes' in el]
            run_nodes = run_nodes[0] if run_nodes else ''
            logger.debug('### Status for {} \n {}'.format(str(node.name),
                                                          run_nodes))
            expected_up = len(n_ctrls) if all_up else 1
            return run_nodes.count('rabbit@') == expected_up
