Fixes#8389#8584.
This PR makes the necessary modifications to officially drop Python 2 support in the Certbot project.
I did not remove the specific Python 2 compatibility branches that has been added in various places in the codebase, to reduce the size of this PR and this will be done in a future one
* Update classifiers and python_requires in setup.py
* Remove warnings about Python 2 deprecation
* Remove Azure jobs on Python 2.7
* Remove references to python 2 in documentation
* Pin dnspython to 2.1.0
* Update changelog
* Remove warning ignore
Fixes https://github.com/certbot/certbot/issues/8134.
* Test on Python 3.9.
* Mention Python 3.9 support in changelog.
* s/\( *'Pro.*3\.\)8\(',\)/\18\2\n\19\2/
* undo changes to tox.ini
* Move more tests to Python 3.9
* Update PyYAML and packages which pinned it back
* Upgrade typed-ast
* Use <= to "pin" dnspython
* Fix lint by telling pylint it cannot be trusted
* Disable mypy on RFC plugin
* add comment about <= support
According to `distutils/version.py`, StrictVersion is pretty strict in
what version numbers to accept:
> A version number consists of two or three dot-separated numeric
> components, with an optional "pre-release" tag on the end. The
> pre-release tag consists of the letter 'a' or 'b' followed by a number.
This assumption already fails for some pretty basic python libraries
itself, like setuptools, also available in `46.1.3.post20200610`, a
completely valid version number according to
https://www.python.org/dev/peps/pep-0440/#post-releases.
There doesn't seem to be a particular reason on why StrictVersion has
been used here, so let's use LooseVersion, to be compatible with these
versions.

Part of #5775. We don't use these docs anywhere, so delete them.
Removes:
- `certbot-compatibility-test/readthedocs.org.requirements.txt`
- `certbot-compatibility-test/docs/` folder
- docs include in `MANIFEST.in`
- docs dependencies in `setup.py`
Fixes#7368.
When updating the changelog, I replaced the line about running tests on Python 3.8 because I personally think that support for Python 3.8 is the most relevant information for our users/packagers about our changes in this area.
* List support for Python 3.8.
* Update changelog.
