Clean up GaleraRestore CRs after successful restore

After database restore completes successfully, automatically delete
the GaleraRestore CRs to clean up restore pods and free resources.

Changes:
- Ansible playbook: Delete GaleraRestore CRs after automated restore
- Documentation: Add cleanup step (step 3) after manual restore
- Helper script: Add optional delete-cr parameter (default: yes)

Automated mode (Ansible playbook):
- Deletes GaleraRestore CRs automatically after successful restore
- Restore pods will terminate
- Clean state for resumed deployment

Manual mode:
- Documentation shows cleanup commands
- Helper script can optionally preserve CR with "no" parameter

Example:
  ./restore-galera-latest.sh openstackrestore        # Deletes CR
  ./restore-galera-latest.sh openstackrestore openstack no  # Keeps CR

This prevents unnecessary resource consumption from restore pods
after the restore operation completes.

 The restore script automatically handles both the database dump and grants file.
 
+**3. Clean up GaleraRestore CRs:**
+
+After successful restore, delete the GaleraRestore CRs to stop the restore pods:
+
+```bash
+# Delete GaleraRestore CRs (automatically done in Ansible playbook)
+oc delete galerarestore openstackrestore -n openstack
+oc delete galerarestore openstackrestorecell1 -n openstack
+
+# Or delete all at once
+oc delete galerarestore --all -n openstack
+```
+
+The restore pods will terminate once the CRs are deleted.
+
 **Future enhancement**: See [README.md#galera-backup-timestamp-tracking](README.md#galera-backup-timestamp-tracking) for proposed solution to timestamp tracking.
 
 After Galera database restore is complete, proceed to the next step.
