Request to Add "username" property to RTCIceServer Object

Hi ,

  I would like to make a request to add optional "username" parameter to RTCIceSever  dictionary to enable one to set the username as part of the configuration.

This change is due to removal of user part from the latest TURN URI Spec: http://tools.ietf.org/html/draft-petithuguenin-behave-turn-uris-03 and hence we need a way to include username outside the uri property of the RTCIceServer object.

Existing:
dictionary RTCIcseServer {
  DOMString  url;
  nullable DOMString credential;
}


Proposes Change:
dictionary RTCIcseServer {
  DOMString  url;
  nullable DOMString username;
  nullable DOMString credential;
}

Thanks
Suhas
