Status of Promise's in gUM discussion

Based on the feedback given to the Strawman consensus position mail [1], 
it seems that there is clear consensus to move to promises for

* navigator.mediaDevices.getUserMedia
* applyConstraints
* enumerateDevices

and we think the editors can start updating the draft to reflect this.

The discussion has not really settled on how to handle backwards 
compatibility with the callbacks based getUserMedia call on navigator.
We'll see if any consensus can be discerned in the coming couple of 
days, if not we'll take a chair's decision on this part.

Stefan for the chairs
