This combines all the different listeners in ExoVideosPlayerV2 into one and
moves the PlaybackLogger class towards ExoPlayer's AnalyticsCollector with
the same purpose.
In the future this allows two things:
1. Gradually move LogginClient implementations to AnalyticsListener to
prevent custom event forwarding.
2. Using ExoPlayer's QoE extension (which is also an AnalyticsListener).
