Zuul/Tox: Install custom python3-keystoneauth1

Some packages available upstream have custom versions
in STX repos. Tests need to be against these custom
dependencies. In this case, distcloud repo requires
python3-keystoneauth1.

This commit adds logic for installing the latest
available STX build of test dependencies.

Test Plan:
pass - Install bindep deps and requirements, then run
       the ansible playbook to install STX deps
       tools/gate/playbooks/install-stx-custom-deps.yaml
       tox -epy39 -c distributedcloud/tox.ini
