Implement RequestNodeNeighborUpdate

[richardthombs]

Hi Rob,

This is my first attempt at getting RequestNodeNeighborUpdate to work. In order to get the Send method to be able to return the appropriate payload, I added an IMessageWithPayload interface which both ControllerFunctionCompleted and UnknownMessage implement (it just returns the payload byte array).

I know it's not very elegant to just return UnknownMessage and I'm happy to do something else instead. Also, I know the way of recognising the return message isn't very pretty either, and again I'm happy to do something else.

Cheers,

R.

Hi Richard,

I've done some refactoring on this one, and I think I've got a good and generic solution: I seems that the RequestNodeNeighborUpdate function sends multiple eventmessages during execution (Started, Done and Failed). So I added a new messagetype ControllerFunctionEvent which represents this message (no more UnknownMessage on this one).

I've implemented this mechanism om RequestNeighborUpdate:

var report = await node.RequestNeighborUpdate();

or if you want progress:

var result = await node.RequestNeighborUpdate((progress) => LogMessage($"RequestNeighborUpdate: {progress} "));
