/** communicates with the NSM
 *  The CAmNodeStateCommunicator communicates with the NodeStateManager via Dbus. Only works, if CAmDBusWrapper is enabled.
 *  The CAmNodeStateCommunicator is triggered via CAmControlReceiver, so you can communicate from the ControllerPlugin with it.
 *  Most if the interfaces are passive, so you get the information you need via retrieving it. If you need to register the AudioManager
 *  as LifeCycleConsumer, you need to call CAmNodeStateCommunicator::nsmRegisterShutdownClient which can be undone with CAmNodeStateCommunicator::nsmUnRegisterShutdownClient.
 *  After you have registered, you will get hookSystemLifecycleRequest on the ControlSendInterface of the controller.
 *  You should answer this within your set timeout with CAmNodeStateCommunicator::nsmSendLifecycleRequestComplete.
