Tenks is used by stable branches of OpenStack projects that are still
using Python 3.9, but dependencies in master upper constraints have
started to drop support for this version [1], since tested runtimes for
2025.2 (Flamingo) target Python 3.10 as a minimum [2].
This replaces support for Python 3.6 which should not be required
anymore (all branches are EOL).
