    rpc: add virNetDaemonSetShutdownCallbacks
    
    The function is used to set shutdown prepare and wait callbacks. Prepare
    callback is used to inform other threads of the daemon that the daemon will be
    closed soon so that they can start to shutdown. Wait callback is used to wait
    for other threads to actually finish.
