Add test_deps role and basic molecule job

This change creates a role named test_dep which will be used by all
roles tested with molecule. This role is iteself is also tested with
molecule. To ensure the CI is able to run these jobs as independent
tox environments a zuul job was setup which will execute setup the
ci node and execute the tox environment.
