Description of problem:
From RHEL8.4 it's possible to use sbd on cluster nodes but not remote nodes, Bug 1443666 as reference.
This RFE is to request the ability to configure it via TripleO template. Now it's required to create a post-deploy script

Version-Release number of selected component (if applicable):
Red Hat OpenStack 16.2 (RHOSP16.2)


Steps to Reproduce:
The script for post-deploy should be similar to this:
~~~
pcs property set stonith-watchdog-timeout=10
pcs resource create watchdog stonith:fence_watchdog

pcs stonith level add 2 controller-0 watchdog
pcs stonith level add 2 controller-1 watchdog
pcs stonith level add 2 controller-2 watchdog

pcs resource update watchdog instance pcmk_host_list="controller-0,controller-1,controller-2"
~~~
Enable sbd in template extra config during the deploy/update:
~~~
parameter_defaults:
   ExtraConfig:
     pacemaker::corosync::enable_sbd: true
~~~


Actual results:
After the configuration the pcs output should be similar to this:
~~~
[root@controller-1 ~]# pcs stonith level
Target: compute-0
  Level 1 - stonith-fence_ipmilan-compute-0
Target: controller-0
  Level 1 - stonith-fence_ipmilan-controller-0
  Level 2 - watchdog
Target: controller-1
  Level 1 - stonith-fence_ipmilan-controller-1
  Level 2 - watchdog
Target: controller-2
  Level 1 - stonith-fence_ipmilan-controller-2
  Level 2 - watchdog
~~~
