[Test] Test self heal of data and hardlink on arbiter
Steps: - Create a volume and mount it - disable metadata,data,entry heal - Create files and take arequal of mount point - Bring down redundant bricks - Append data and create hardlinks - Bring up bricks - Check healing and split-brain - Bring down redundant bricks - Truncate data - Check file and hardlink stat match - Bring up bricks Change-Id: I9b26f2fb26d72b71abd63a25ef8d9173f32997d4 Signed-off-by: ubansal <ubansal@redhat.com>
