+ Test for snapshot create during rebalance

+ 4. Create one snapshot with option no-timestamp
+ 5. Add bricks to the volume using gluster volume
+ 6. Start Rebalance using gluster v rebalance <vol-name> start
+ 7. While rebalance is in progress, create gluster snapshot
+ -snapshot creation should fail with message : rebalance is runinng

+ 9. After rebalance is completed, create snapshots with the same name as
