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.

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 prevents unreleased versions appearing on the website (e.g. 0.3.5.dev0),
but introduces the risk of forgetting to update the website after a release.
A better fix requires deeper design/workflow thought.

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.

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):

ModuleNotFoundError: No module named 'tox.config.parallel'
```
faulthandler is a stdlib module in Python 3.3+. For a long time a PyPI package
of the same name was available for earlier Python releases. That package has
since been removed from PyPI, and the source respoitory archived. So we should
not rely on it.

I'm not 100% confident that merely removing this is the full fix,
without substituting something else. I am sure keeping it would be
the greater of two evils. __del__() should be avoided on general
principal, and it's associated with multiple intermittant CI
failures, plus multiple user reported issues.
Until Ansible 2.9 it looks like ansible_become_password had higher priority.
From Ansible 2.10 ansible_become_pass has higher priority [1]. Mitogen was not
respecting this.
I may need to rework this further, instatiating the become plugin may have
slowed down execution.
[1] Based on testing with
```
[ubuntus]
become-pass-pass ansible_become_pass=1234
become-pass-password ansible_become_password=1234
become-pass-both ansible_become_password=wrong ansible_become_pass=1234
