[tripleo][tripleo-ansible] Reigniting tripleo-ansible

Hey Sorin,

I'm glad to see you are excited as we are about this effort! Since you are
one of the core developers of Molecule, I was hoping to get some of your
insight on the work we have started in that regard. I have a few patches up
for adding in Molecule tests to tripleo-common. At a later point in time,
we can discuss the transition of moving all of the Ansible content into the
tripleo-ansible repository.


The first is to add the common files that will be used across most, if not
all, of the Molecule tests in this repository. The second patch is where I
actually implement Molecule tests and symlinks to those common files in the
first patch. I wanted to get your thoughts on a few things.

1. How would we hook in the Molecule tests into tox so that it will be
tested by CI? Do you have an example of this already being done? I believe
from previous discussions you have already added a few Molecule tests to a
TripleO repository before. Kevin also had a good ideal of creating an
isolated Zuul job so that can be something we can investigate as well.
2. How should we handle the actual tests? In the second patch, I used the
playbook.yaml to write the test in a playbook format (the actual test
happens during the post_tasks phase). I have always done Molecule testing
this way to keep things simple. However, would you recommend that we use
the Python testinfra library instead to make sure that certain things exist?

Thanks for any input you may have!
