Callback function to get node/sensor information's

[jkandasa]

For now as per my knowledge, to learn about MySensors node network, controller should send I_REBOOT command to nodes(1 to 254). I am feeling this might case issue for some nodes which is in production field. We need a mechanism to present node details when there is a request from gateway/controller.

For this we should give a callback function option, hence user can put their node/sensors presentation details. Whenever "Who are you?" call comes node will present like "My Name is......and I have........"
