Spark-742: TaskMetrics should not employ per-record timing.

This patch does three things:

1. Makes TimedIterator a trait with two implementations (one a no-op)
2. Makes the default behavior to use the no-op implementation
3. Removes DelegateBlockFetchTracker. This is just cleanup, but it seems like
   the triat doesn't really reduce complexity in any way.

In the future we can add other implementations, e.g. ones which perform sampling.
Modified version of the fix which just removes all per-record tracking.

Added a shuffle block manager so it is easier in the future to
consolidate shuffle output files.
Allow specifying the shuffle write file buffer size. The default buffer
size is 8KB in FastBufferedOutputStream, which is too small and would
cause a lot of disk seeks.
