This CL replaces the old storage system with the storage muxer system. In addition to replacing the old system, this CL removes all the code that was only used by the old system. As of this change Storage Muxer support shaka player's V1, V2, and V2 indexeddb schemes and exposes a plug-in system for other offline storage components.
