Add play/pause buttons for video preview
Added custom play & pause controls for video preview. These override the
default Play/Pause drawables from ExoPlayer.
On preview of first video - we show the controls and auto hide the
buttons.
onTouch - Show/Hide controls. If onTouch shows controls, controls remain
sticky until next event.
on play - Controls will auto hide in 1s
on swipe - We show controls only if the previous video had controls
visible or if the previous page was a non-video page.
on pause - Controls will remain sticky until next onTouch event.
