Remove / change some places that are long deprecated or no longer
needed:
- openstack-common.conf - was used for pulling code from oslo-incubator,
but that is dead for at least 8 months already.
- deploy.yaml playbook - declared as deprecated more than a year ago
- enroll.yaml playbook - declared as deprecated more than a year ago
- a task and var in bifrost-test-vm role - deprecated test
playbooks were removed recently, and their handling in this role is no
longer needed.

Use cookiecutter (https://git.openstack.org/openstack-dev/cookiecutter)
to generate config for tox so we can generate docs, run pep8, etc.
Also move CONTRIBUTING.rst to the root of the repository in keeping
with what seems to be the standard location. This move allows us to
easily generate the docs. Also include a tiny fix to allow pep8 to
run cleanly.
