    Change the restart_rpc_backend loop to accomodate async rabbitmq
    
    Some distros have converted to systemd for starting RabbitMQ.  This has
    resulted in:
    ---
    [Call Trace]
    ./stack.sh:904:restart_rpc_backend
    /home/stack/projects/openstack/openstack-dev/devstack/lib/rpc_backend:201:die
    [ERROR] /home/stack/projects/openstack/openstack-dev/devstack/lib/rpc_backend:201 Failed to set rabbitmq password
    Error on exit

    Because 'restart_service rabbitmq-server' returns before the server is ready to
    accept connections.
    
    Alter the retry loop to only restart the rabbitmq-server every second time
    through the loop.  Allowing time for the slow rabbit to start.
