[PATCH v7 1/6] CI: make Python version configurable

["Oliver Steffen" <osteffen@redhat.com>]

Add a new parameter "usePythonVersion" to the CI job templates.
This makes it possible to specify the version of Python to use.
The default value is ">=3.10.6".
If '' is specified, Python will not be downloaded at runtime and
the one provided by the VM/container image will be used.
