cluster/afr : Prevent inode-evict during split-brain resolution
1) Provided setfattr command to set timeout for split-brain choice. 2) If split-brain inspection/resolution is being done from the mount for a file, ref the inode when split-brain-choice is set. This inode will be unconditionally unref-ed after timeout seconds set by the user/default otherwise. 3) Updated the doc and testcase to reflect the changes.
