Increase unit test job timeout to an hour
Increase unit test job timeout to an hour

Declare variants of the tox-py27 and tox-py35 jobs with a one-hour
timeout instead of the default half-hour. Since we're declaring
these here in the repository, we can also add tox-pep8 and
publish-openstack-python-branch-tarball so that the
openstack-python-jobs-no-constraints and
openstack-python35-jobs-no-constraints templates can be removed from
project-config later.
