Add support for pulling translations from Zanata

To help move to Zanata, we should pull down translations from
the server. Add a function that should behave the same way as
the existing Transifex function, as well as changing two existing
scripts to call it based on a command-line parameter. Add two new
jobs with a -zanata suffix so we can switch projects one at a time.

This change deals with all of the Python projects and
django_openstack_auth. Horizon and OpenStack manuals will be dealt with
in a future patch.
