Provide cache-aware adaptive track selection

### [REQUIRED] Searched documentation and issues
Looked into release notes and into the issue list in Github

### [REQUIRED] Question
While exoplayer is in process of HLS streaming with cache enabled, Due to its adaptive streaming property it caches different quality of chunks based on network condition.
So my question is, if a song is completely cached but in different quality of chunks, is it possible to restrict the player that it should play from cache only, whatever the quality of chunk is present in the cache, irrespective of Network condition.

### A full bug report captured from the device
This not about bug, but a functionality support which I need to implement in my use case.
