Fixes https://github.com/certbot/certbot/issues/7913.
I only added the deprecation warning to `certbot.tests.util` because that's the only place where I think someone could be using the `mock` module through our API.
* remove external mock from acme
* update Certbot's mock usage
* remove mock dependency in plugins
* remove external mock from compatibility test
* add changelog entry
Part of #7886.
This PR conditionally installs mock in `acme/setup.py` based on setuptools version and python version, when possible. It then updates `acme` tests to use `unittest.mock` when `mock` isn't available.
Now with `type: ignore` as appropriate. Once the "future steps" of #7886 are finished, and mypy is on Python 3, the `pragma no cover`s and `type ignore`s will be gone.
* Conditionally install mock in acme
* error out on newer python and older setuptools
* error when trying to build wheels with old setuptools
* use unittest.mock when third-party mock isn't available in acme, with no cover and type ignore
* Revert "Do not require mock in Python 3 in certbot module (#7895)"
This reverts commit 77871ba71c.
* Revert "Do not require mock in Python 3 in acme module (#7894)"
This reverts commit cd0acf5dcc.
