Thanks to Daryn for handing over the change he made in getDefaultBlockSize and getDefaultReplication.

> {{ViewFileSystem}} incorrectly returns the {{FileSystem}} default values for {{getDefaultBlockSize()}}
and {{getDefaultReplication()}}.  This causes files to be created with incorrect values. 
The problem is that the current apis are insufficient for viewfs because the defaults depend
on the underlying mount point.  These methods need counterparts that accept a {{Path}} so
viewfs can resolve the mount point for a path.
