Added missing execution plan

Execution plan to patch existing k8s services to include node IPs
when number of nodes changed and we are not using gateways
or we was using gateways and now we don't

These 2 files were supposed to be in
https://review.openstack.org/#/c/175506/
but I forgot to commit them

Also fixes typo that is already fixed in stable/kilo
