Fix group of lights

[fmeies]

A group of lights like this

Group:Switch:OR(ON,OFF) lightGroup ["Lighting"]
Color light1 (lightGroup) ["Lighting"]
Color light2 (lightGroup) ["Lighting"]

is not discovered correctly. In v2, the individual lights as well as the group of lights are discovered. In v3, only the individual lights are discovered.

I guess we have to distinguish between "endpoint" groups like e.g., Alexa.Endpoint.Thermostat or Alexa.Endpoint.Speaker and "simple" groups like a group of lights or rollershutter items.

What do you think?

Take a look at eclipse-archived/smarthome#4390 (comment) , I'm going to redo using tags for metadata instead. This should not be too different, but I wonder if we can improve the group issue, i have not had time to look at it yet. In any case we will still support v2 tags.

Also I apologize for some sloppiness in the code with things commented out and random log statements, this was my personal branch and was not anticipating others to share, but I definitely welcome the help!

Thank you for your feedback. I'll have a look at the referenced metadata discussion.

One of the changes I submitted was to use the latest openhab state opposed to the original requested state in Alexa response messages. If @digitaldan is fine with that, this change wouldn't be necessary.
