Since we've started storing deployment plans in swift, there is a collision with this name, because the "overcloud" plan will by default get deleted when deleting a stack, which is a regression if you're a user of one of these scripts, because previously you only had to re-run them e.g if your puppet modules changed, not every deploy.
