[lib] Adding collect_bricks_arequal() to lib_utils.py
Adding function collect_bricks_arequal() to lib_utils.py to collect arequal-checksum on all the bricks of all the nodes used to create a volume using the below command: ``` arequal-checksum -p <BrickPath> -i .glusterfs -i .landfill -i .trashcan ``` Usage: ``` >>> all_bricks = get_all_bricks(self.mnode, self.volname) >>> ret, arequal = collect_bricks_arequal(all_bricks) >>> ret True ``` Change-Id: Id42615469be18d84e5691c982369634c436ed0cf Signed-off-by: kshithijiyer <kshithij.ki@gmail.com>
