    neutron-server: Remove start/sleep/stop pattern

    Currently the bootstrap of the neutron server happens with the use of a
    start/sleep/stop pattern.

    Since Pacemaker doesn't mind if the service is already started let
    simply start the neutron server on the $pacemaker_master node and wait
    for 5 sec.
