1. Remove monitor op from stonith-sbd …

   I removed    op monitor interval="15" timeout="15" from stonith-sbd. 
   With multiple SBD disks, in case one disk failed, the monitor operation will detect a failure and pacemaker will try to restart stonith-sbd resource on all node and the start will fail and stonith-sbd become inactive. 
   stonith-sbd    (stonith:external/sbd): Stopped
   
   Removing above monitor operation, the system will log failure messages in logs but resource will not restart.
