This looks pretty good to me API-wise, but an Option[Boolean] is kind of
confusing. Maybe we should have an enumeration called SortOrder and pass in an
Option[SortOrder].
Also, when this value is set, please add a check that keyOrdering is also
set. Otherwise the user made an error in configuring the ShuffleDependency but
we'll just return unsorted data.
We should also wait on #931 to be merged and then base this on that.
