Pacemaker resource agent ocf:heartbeat:oralsnr: tns_admin attribute requires unique

Issue

• Since pcs-0.9.167-3.el7.x86_64 the tns_admin unique requirement is enforced.

• Creating a resource with a duplicate tns_admin will fail:

  # pcs resource create rs_oraclsnr_01 ocf:heartbeat:oralsnr home=/u021/app/oracle/product/12.1.0.2 listener=LISTENER_01 sid=01 tns_admin=/network/admin user=oraclp op methods interval=0s timeout=5 monitor interval=10 timeout=30 start interval=0s timeout=120 stop interval=0s timeout=120
  # pcs resource create rs_oraclsnr_02 ocf:heartbeat:oralsnr home=/u01/app/oracle/product/12.1.0.2 listener=LISTENER_02 sid=02 tns_admin=/network/admin user=oraclp op methods interval=0s timeout=5s monitor interval=10 timeout=30 start interval=0s timeout=120 stop interval=0s timeout=120
  Error: Value '/network/admin' of option 'tns_admin' is not unique across 'ocf:heartbeat:oralsnr' resources. Following resources are configured with the same value of the instance attribute: 'rs_oraclsnr_01', use --force to override
