I just learned this module exists. Thanks for reaching out!

By looking at the source code, it looks like this is exactly what we need and
what we were hoping to come up with. YAY! Open Source! YAY! OpenStack!

As mentioned on IRC, I'll add validation to this module (check the keys actually
exist, the types are valid, etc) based on the YAML schema that can be generated
with oslo-config-gen now.

I'll reach out again as asoon as I have something to show on this front.
Thanks again for your work,
Flavio
