Gah not quite there. I use meta_end play when I calculate that a patch
isn't relevant so that we don't spend time decomissioning a host that
doesn't need a patch. Problem is this skips the post_tasks if the last
server in the group isn't relevant. I tried using handlers but that results
in 1 execution per node.
I think I might need to re-think my playbook organization and simplify. I
could use a workflow in tower to accomplish this simpler without skipped
tasks.
