Summary: Rename HashShufflereader to BlockStoreShuffleReader (was:

ShuffleManager.getReader())
> Rename HashShufflereader to BlockStoreShuffleReader
> ---------------------------------------------------
>
> Key: SPARK-10704
> URL: https://issues.apache.org/jira/browse/SPARK-10704
> Project: Spark
> Issue Type: Sub-task
> Components: Shuffle
> Reporter: Josh Rosen
> Assignee: Josh Rosen
>
> The current shuffle code has an interface named ShuffleReader with only one
> implementation, HashShuffleReader. This naming is confusing, since the same
> read path code is used for both sort- and hash-based shuffle. We should
> consolidate these classes.
> In addition, there are aspects of ShuffleManager.getReader()'s API which
> don't make a lot of sense: it exposes the ability to request a contiguous
> range of shuffle partitions, but this feature isn't supported by any
> ShuffleReader implementations and isn't used anywhere in the existing code.
> We should clean this up, too.
