Added enableBackgroundUpdates option for each LiveObjectSynchronizer

[huntj88]

Added enableBackgroundUpdates option for each LiveObjectSynchronizer instance. This flag is set to false on LiveMediaSession.

Replaced joined event in LiveMediaSession with LiveObjectSynchronizer connect event. This cuts down on an additional signal sent by every client when first joining the session.

validation: LiveMediaSession object Id: 515a1cdd-afdc-4bd3-8c4f-1f01641c7754

LiveMediaSession initial data is part of connect signal.
