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.

importlib.machinery.ModuleSpec and find_spec() were introduced in Python 3.4
under PEP 451. They replace the find_module() API of PEP 302, which was
deprecated from Python 3.4. They were removed in Python 3.12 along with the
imp module.
This change adds support for the PEP 451 APIs. Mitogen should no longer import
imp on Python versions that support ModuleSpec. Tests have been added to cover
the new APIs.
CI jobs have been added to cover Python 3.x on macOS.

To do so the test suite allows a weak cryptographic alogorithm (SHA1) to be
used, principally for CentOS 6 targets. This can be removed if/when support
for older (legacy) targets is dropped.
Only the test suite enables this known weak alogorithm. Mitogen as-shipped
doesn't enable or disable algorithms.
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
These are not part of the official testing regime (tests run for pull
requests). I find them convenient for local development.
Limitations
- Python 2.7+ only. No Python 2.4, 2.5, or 2.6.
- Requires Pythons pre-installed (e.g. DeadSnakes, pyenv)
- No coverage of alternate controller OS (e.g. MacOS)
The environments tested by default are
py27-mode_ansible-ansible2.10
py36-mode_ansible-ansible2.10
py39-mode_ansible-ansible2.10
py27-mode_mitogen
py36-mode_mitogen
py39-mode_mitogen
py27-mode_mitogen-distro_centos7
py36-mode_mitogen-distro_centos7
py39-mode_mitogen-distro_centos7
Python 3.0 to 3.4 are excluded because no version of Ansible supports
them. Due to their setup.py declarations pip refuses to install Ansible
on these versions of Python.
This means test files are imported as modules, not run as scripts. THey
can still be run individually if so desired. Test coverage is measured,
and an html report generated in htmlcov/. Test cases are automativally
discovered, so they need not be listed twice. An overall
passed/failed/skipped summary is printed, rather than for each file.
Arguments passed to ./test are passed on to unit2. For instance
./test -v
will print each test name as it is run.
