/** 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.
