[webrtc-pc] Missing sender identifier attribute

jcaden has just created a new issue for 
https://github.com/w3c/webrtc-pc:

== Missing sender identifier attribute ==
`replaceTrack` documentation says: 
 
> To avoid track identifiers changing on the remote receiving end when
 a track is replaced, the sender must retain the original track 
identifier and stream associations and use these in subsequent 
negotiations.

At this point, I can't see a way to get the identifier that a sender 
is using. If you don't execute `replaceTrack`, you can use track's 
identifier, but if you change the track there is no way to get it.

It will be great to add a public attribute in the API providing access
 to the identifier that is being used by the sender.
