Currently if you go to https://certbot.eff.org/docs/api/certbot.crypto_util.html, there is a todo comment displayed at the top of the page. These todos were written for developers, not users, so I do not think they should be shown from our documentation.
This PR makes the quick and easy fix of configuring Sphinx not to show these todo items. I created #7752 to track removing all of these todos from our docstrings and disabling the Sphinx todo extension.
* Set todo_include_todos=False in sphinx-quickstart
* Remove todos from existing docs.
It looks like we're currently documenting functions that are marked private (prefixed with an underscore) such as https://certbot.eff.org/docs/api/certbot.crypto_util.html#certbot.crypto_util._load_cert_or_req. I do not think we should do this because the functionality is private, should not be used, and including it in our docs just adds visual noise.
This PR stops us from documenting private code and fixes up `tools/sphinx-quickstart.sh` so we don't document it in future modules.
* Do not document private code.
* Don't document private members in the future.
Creates documentation boilerplate for certbot-dns-route53 using
tools/sphinx-quickstart.sh.
Adds trivial `authenticator.rst` and `dns_route53.rst` files.
