Browse source 
* Handle bitrate change by finding the stream with closest bitrate as peer

* Convert video id into bitrate when creating peer or changing bitrate

* Try to fix prometheus panic

* Revert metrics label name change

* minor fixes.

* bitrate selector.

* skip if moving to the same stream.

* no closure for getting target bitrate.

* fix: high res switch to lo video, stream bitrate out of range

* revert dev config change.

* white space.
