As a developer of OCPEDGE, I need:

• A script to help a user update fencing credentials in pacemaker.
• The script should then update the credentials via the secret in openshift-etcd.
• The script should verify that pacemaker's errors are resolved.

Acceptance Criteria

• The script is written and merged into openshift-etcd.
• The script is documented.
• A new e2e test is added to openshift/origin to validate this as part of the TNF recovery repo.
