I want to use isort as part of https://github.com/certbot/certbot/issues/9572 because I want to do it programmatically, however, I felt like the config needed to be tweaked a bit due to it not understanding what is and is not our own code.
This PR updates the isort config so it recognizes our own modules and runs `isort .` from the root of the repo to update everything.
* update isort config
* run "isort ."
