Bump container from python3.10 to python3.11

This matches what Zuul and Nodepool are doing. Getting off the older
images will also allow OpenDev to stop building them. We update the
unittest job to python 3.11 in the process to better cover what people
will deploy.

Note we wanted to update the base OS from bullseye to bookworm, but this
update involves upgrading openssl from 1.1.x to 3.x and the rehash
library which the registry depends on is not compatible with openssl
3.x. Getting to python3.11 on bullseye would at least allow us to stop
building python3.9 and python3.10 bullseye images.
