Adding test for profile operations with one node down

Test Case:
1) Create a volume and start it.
2) Mount volume on client and start IO.
3) Start profile info on the volume.
4) Stop glusterd on one node.
5) Run profile info with different parameters and 
   see if all bricks are present or not.
6) Stop profile on the volume.
