This adds a useful hook to be used for projects that use stestr,
it is primiative at the moment but covers most scenarios for using
it.
This PR also changes a Python module to start using it, once it
lands, follow up PRs can update all of them to use it tree-wide.

Fixes#476822 and #480467 . By itself this change doesn't trigger many
rebuilds, but it is easier to justify it in conjunction with the
previous commit.

If Nix supports lazy attribute names in the future,
this change will make `<python package>.override` warning-free
and make such warning (or future throw) remediateable
via another override.
There is no need to disable Python packages for Python versions that are
no longer in Nixpkgs.
This change was generated using the following script:
pattern='^\s*disabled\s*=\s*pythonOlder\s*"3\.\([0-9]\|10\)"\s*;\s*$'
for f in $(find -name '*.nix'); do
grep -q "$pattern" "$f" || continue
sed -i "/$pattern/d" "$f"
if [ $(grep -c pythonOlder "$f") == 1 ]; then
sed -i '/^\s*pythonOlder,\s*$/d' "$f"
fi
nixfmt "$f"
done
