[rdo-list] Packstack refactor and future ideas

If it is not tested, it doesn't work, by definition.
We want to ensure, with resources available, that Packstack works well
in the future for the use-case it was designed for, proof-of-concept
installations.
For production installations TripleO is recommended.

Cheers,
