Release Note:Adds a 'HardLink', an hfile proxy that tolerates files being moved from original location out to archive; it will find and serve the data whichever location the file happens to be in.
To avoid copying data during restore snapshot we need to introduce an HFile Link that allows to reference a file that can be in the original path (/hbase/table/region/cf/hfile) or, if the file is archived, in the archive directory (/hbase/.archive/table/region/cf/hfile).
