Subject: afr: add mtime based split-brain resolution to CLI

Backport of http://review.gluster.org/#/c/13828/

Extended the CLI to include support for split-brain resolution based on
mtime. The command syntax is:

$:gluster volume heal <VOLNAME> split-brain latest-mtime <FILE>

where <FILE> can be either the full file name as seen from the root of the
volume (or) the gfid-string representation of the file.
