* During the release, reset local-oldest-requirements.txts that might have been changed during development.
* only modify the file if it exists
* no need to specifically add certbot-compatibility-test because it doesn't have the file anyway
* Use double quotes instead of single
* escape dots and brackets
* Escape and quote correctly
Currently the release script in master fails for a few reasons. First, it's trying to use --numprocesses which comes from a pytest plugin that we're not installing in the release script. Second, many new warnings are raised when we're not using pinned versions of our dependencies.
I'm not sure I agree, but one could argue that we should fix these issues and use the file during the release. I'm particularly hesitant for us to do this when it comes to warnings. We currently do not pin our dependencies in the release script. Do we really want to stop the release because a new package was released and is warning about something? One could argue we do because these warnings may be visible to the user, but they very rarely are and I think this makes the release process much too painful.
I especially do not think we should block the release on this now as we are not up to date on the warnings raised by the latest versions of our packages so there is a lot to work through.
* Don't use pytest.ini during the release.
* State that pytest.ini isn't used in release script.
* Automation for changelog changes during release
* Update changelog during release before modifying version numbers
* don't link to the GitHub repo
* no need to sign the commit bumping version numbers
* simplify tail call
