Description of problem:
The current implementation of the Auto-fencing is not user friendly. The way in which it used now is by running twice the opnestack deployment command which takes a lot of time on medium and large environments.
current way:
1) $DEPLOYCOMMAND
2) openstack overcloud generate fencing -a reboot --ipmi-lanplus --ipmi-level
administrator --output fencing.yml instackenv.json
3) $DEPLOYCOMMAND -e fencing.yml
