Update afsmon python testing to modern versions

We run this tool primarily on our mirror-update nodes which are
currently Focal with python3.8. We want to drop the python35 testing so
that we can clean up our Xenial test nodes. Update afsmon's testing to
more closely match the current production environment and potential
future environments while also dropping python35 on Xenial jobs.

Small changes are made to fix a string escapes warning and a use of mock
error when running flake8.
