Add generic base and base-test jobs/playbooks

Start with a stripped-down fork of the base job from project-config,
omitting any OpenStack-specific roles and variables. Also include a
duplicate base-test job intended for testing out potential changes
to the base job.

Extend the linters env for tox to check the included playbooks with
ansible-lint.
