The ensure-python role used by most of OpenStack's test jobs
supports installing Python in other ways than from distro packages
already, that just happens to be its default method. If you set the
python_use_pyenv[*] flag then it will clone and install pyenv[**]
from GitHub and proceed to build the requested Python
interpreter/stdlib version.

The main downsides I see for not using a prebuilt Python packages is
that the effected jobs are going to end up building Python from
source on every run, and there's still no guarantee that we have an
available platform where the requested Python version can be built
successfully.
