[SPARK-2977] Ensure ShuffleManager is created before ShuffleBlockManager
This is intended to fix SPARK-2977. Before, there was an implicit ordering
dependency where we needed to know the ShuffleManager implementation before
creating the ShuffleBlockManager. This patch makes that dependency explicit by
adding ShuffleManager to a bunch of constructors.
I think it's a little odd for BlockManager to take a ShuffleManager only to
pass it to ShuffleBlockManager without using it itself; there's an opportunity
to clean this up later if we sever the circular dependencies between
BlockManager and other components and pass those components to BlockManager's
constructor.
