Open Stack

Doug recently introduced the template publish-to-pypi-python3 and used
it for all official projects. It only has a minimal python3 usage
(calling setup.py sdist bdist_wheel) that should work with any repo.

Thus, I pushed a a series of changes up - see
https://review.openstack.org/#/q/topic:publish-pypi - to rename
publish-to-pypi-python3 back to publish-to-pypi. Thus, everybody uses
again the same template and testing.

Note that the template publish-to-pypi-python3 contained a test to see
whether the release jobs works, this new job is now run as well. It is
only run if one of the packaging files is updated - and ensures that
uploading to pypi will work fine. If this new job now fails, please fix
the fallout so that you can safely release next time.

The first changes in this series are merging now - if this causes
problems and there is a strong need for an explicit python2 version,
please tell me,

Andreas
