A fix was rushed out to resolve https://bugs.launchpad.net/tripleo/+bug/1621462. It only ever passed CI because the default plan creation wasn't working - this meant that the plan was never being updated.
The problem can be seen here as it resolved the default plan, and then CI attempts to do an update to it and deploy which then fails. https://review.openstack.org/#/c/368760/
We need to:
1. Fix the plan updating
2. Land the fix for the default plan
3. Make sure CI is verifying the default plan and fails if it doesn't work.
