Update gear to python3.11 and Bookworm container

This is motivated by OpenDev's desire to drop the old Bullseye container
images as well as container images for older versions of python. We bump
testing to python3.11 on the high end of the range and convert the
container image to python3.11 + Bookworm.

Python 2.7 testing is removed because tox + virtualenv can't actually
create python2.7 virtualenvs any longer. There are workarounds but
dropping the tests is simpler.

Python 3.5 testing is replaced with 3.6 testing beacuse the version of
easy_install on ubuntu xenial does not understand TLS + SNI. A while
back pypi.org dropped non SNI connection support which means we can't
install PBR for to run the setup.py for the projcet. There are
workarounds but 3.5 is old enough taht we should be able to move on.
