Most of the necessary changes were made in recent PEP 451 commits. This bumps
the CI jobs, and declares the support. Test dependendancies are bumped to
latest supportted/available versions.

With current macOS 11 runner images (20231216.1) the `python` on `$PATH` is
Python 3.12 and setuptools isn't installed by default. E.g.
```
python -mtox -e "py27-mode_localhost-ansible4"

Installing setuptools under Python 3.12 chooses package versions incompatible
with Python 2.7. Additionally Mitogen isn't yet compatible with Python 3.12
(#1033), so tests that call a local context with `python` fail.
This should address the warning in Azure Pipelines
> You should provide GitHub token if you want to download a python release.
> Otherwise you may hit the GitHub anonymous download limit.
The token is provided from a secret variable in the pipeline.
I'm abandoning tox-factor because having any [tox] requires = ... causes tox
3.x to create an isolated virtualenv for running tox itself. Since Tox 4.x was
released that virtualenv gets it, which is incompatible with the tox-factor
plugin.
e.g.
```
Traceback (most recent call last):
File
"/Users/runner/work/1/s/.tox/.tox/lib/python3.10/site-packages/tox_factor/compat.py",
line 2, in <module>
from tox.config.parallel import ENV_VAR_KEY_PUBLIC as TOX_PARALLEL_ENV
ModuleNotFoundError: No module named 'tox.config.parallel'
```
Also
- Simplifies adding support for additional Ansible versions
- Unifies Python package versioning in CI and local test environments
- Matches Python versions tested, with those declared in setup.py
- Expands targets covered by automated Ansible tests to
- centos6, centos8
- debian9, debian11
- ubuntu1604, ubuntu2004
This reverse shell was historically used to debug CI jobs interactively.
It is not used anymore, and may be causing jobs to hang, then timeout.
There is no reason to keep it, and removing it simplifies CI jobs.
Additionally it has been reported as flagged by security scanners, so
removing it makes Mitogen easier to package/adopt.
