Add Python 3.11 testing

This adds python 3.11 testing and drops python3.10 in order to keep
testing only the bounds of what Zuul supports. Note that currently the
python 3.11 available for jammy is based on an RC release. This should
be fine as we do functional testing with a released python 3.11 and that
is what people will consume via the docker images.
