* feat: Use source name based receiver constraints
* add sourceNameSignaling feature flag to config
* move source name specific variables into if block
* ensure sourceName is defined in constraints
* use source name for selectedSources
* use selector to find video track by participant id
* add selector to encapsulate logic to get track source name
* refactor getTrackSourceNameByMediaTypeAndParticipant selector
* rename variable
* move flags config into Feature Flags section
* do not set constraints for local large video
* rename prioritizedSources to onStageSources
* fix flow error
* refactor visibleRemoteTrackSourceNames to a constant
* use selector to get feature flags
* rename selector function
* fix flow error
* add selector for sourceNameSignaling feature flag
* feat(Filmstrip): Reorder the visible participants in the filmstrip.
The participants are ordered alphabetically and the endpoints with screenshares, shared-videos and dominant speakers (in that order) are bumped to the top of the list. The local participant is also moved to the top left corner as opposed to the bottom right corner.
* squash: Implement review comments.
* squash: store alphabetically sorted list in redux and move shared videos to top.
* squash: Use the DEFAULT_REMOTE_DISPLAY_NAME from interfaceConfig for users without a display name.
The client now listens for changes to lastN, selectedEndpoints and maxReceiverVideoQuality in redux to trigger sending bridge message in the new format. This fixes an issue where the stage view <-> tile view changes prompt two receiver constraints messages to be sent, first with the maxHeight update and then with the selected endpoints update.
