Fixes https://github.com/certbot/certbot/issues/9058.
The changes to the CI config are equivalent to the ones made in https://github.com/certbot/certbot/pull/8460.
Other than ignoring some warnings raised by botocore, the main additional work that had to be done here was switching away from using `distutils.version.LooseVersion` since the entire `distutils` module was deprecated in Python 3.10. To do that, I took a few different approaches:
* If the version strings being parsed are from Python packages such as Certbot or setuptools, I switched to using [pkg_resources.parse_version](https://setuptools.pypa.io/en/latest/pkg_resources.html#parsing-utilities) from `setuptools`. This functionality has been available since [setuptools 8.0 from 2014](https://setuptools.pypa.io/en/latest/history.html#id865).
* If the version strings being parsed are not from Python packages, I added code equivalent to `distutils.version.LooseVersion` in `certbot.util.parse_loose_version`.
* The code for `CERTBOT_PIP_NO_BINARY` can be completely removed since that variable isn't used or referenced anywhere in this repo.
* add python 3.10 support
* make some version changes
* don't use looseversion in setup.py
* switch to pkg_resources
* deprecate get_strict_version
* fix route53 tests
* remove unused CERTBOT_PIP_NO_BINARY code
* stop using distutils in letstest
* add unit tests
* more changelog entries
Apache test farm tests started failing last night due to a change in pyenv. See https://dev.azure.com/certbot/certbot/_build/results?buildId=3948&view=logs&j=f67c2a39-2c4f-5190-915f-6f32a7a4306f&t=96f0f394-f513-5158-f5e7-a26e55aeadbf&l=26943.
I managed to fix that in d94f20f8b7, however, the OSes the tests were failing on were Debian 9 and Ubuntu 16.04. [Debian 9 reached its end-of-life in July 2020](https://wiki.debian.org/DebianReleases) and [Ubuntu 16.04 reached its end of standard support in April 2021](https://wiki.ubuntu.com/Releases). As shown at the same links, Debian 9 still has support from the LTS team and Ubuntu 16.04 has ESM support. Do we still want to support either of these OSes?
If so, we can use the commit I linked in the first sentence of the last paragraph, but I think supporting the OSes through their standard support is good enough. The Certbot team has enough on their plate and especially when the OSes are so old that we can't even use their packaged version of Python anymore which complicates our tests, I think we can just drop support and move on.
I don't have a strong opinion here though so if someone else does, let me know what you'd like to see or make the PR yourself based on the changes in my linked commit and I'll merge it.
You can see the tests passing with this change at https://dev.azure.com/certbot/certbot/_build/results?buildId=3955&view=results.
* Remove apache tests on old OSes
* remove unused pyenv code
Fixes https://github.com/certbot/certbot/issues/8781.
This PR makes our test farm tests into a normal package so it and its dependencies can be tracked and installed like our other packages.
Other noteworthy changes in this PR:
* Rather than continuing to place logs in your CWD, they're placed in a temporary directory that is printed to the terminal.
* `tests/letstest/auto_targets.yaml` was deleted rather than renamed because the file is no longer used.
* make a letstest package
* remove deleted deps
* fix letstest install
* add __init__.py
* call main
* Explicitly mention activating venv
* rerename file
* fix version.py path
* clarify "this"
* Use >= instead of caret requirement
