Upgrade cloud media thumbnail API
We refactored the thumbnail API to a more generic preview API. This
supports fetching image and video previews.
This is necessary for apps that might not support the advanced
SurfaceController API for video playback. It will allow them return a
preview quality video instead of the potentially large original
quality.
Also addressed some pending API review comments
