Until now if there is a nit inside any
Ansible task part of tripleo-heat-templates we will
need to wait until the end-to-end test imports
the actual tasks to fail.
This submission adds the hability to run a syntax
check for any Ansible task part of any role
defined by default in the resource registry.
Also it will allow to reduce the CI CO2 footprint
by not executing unneeded jobs meant to fail.
Let's save the planet and some CI cycles.
