Stop caching the results of ipv6_info in http01.py. A call to choose_vhosts might change the ipv6 results of later calls. Add tests for this and default_listen_addresses more broadly.
Previously, Nginx did not allow `${` to start a variable name. Now it's allowed to. This means we'll be more permissible than Nginx when people are on older versions of Nginx, but it's unlikely anyone was relying on this to fail in the first place, so that's probably ok.
This makes errors more useful when Nginx can't be found or when Nginx's
configuration can't be found. Previously, a generic
`NoInstallationError` isn't descriptive enough to explain _what_ wasn't
installed or what failed without going digging into the source code.
* Exclude one-time use parameters. Fixes#6118
* Fix error.
* Delete items inplace, rather than creating new list.
* Fix stupid mistake.
* Use .index() for stability.
* Try previous idea while resetting the index.
* Shorter comment for pylint.
* More readable approach
* Fix whitespace
* Use greater than or equal to in requirements.
This changes the existing requirements using strictly greater than to greater
than or equal to so that they're more conventional.
* Use >= for certbot-postfix.
Despite it previously saying 'certbot>0.23.0', certbot-postfix/local-oldest-requirements.txt was pinned to 0.23.0 so let's just use certbot>=0.23.0.

nginx:

* Show both possible Nginx default server root values in docs
* add test
* check that exactly one server root is in the default
* use default magic
* automatically select among default vhosts if we have a port preference
* ports should be strings in the nginx plugin
* clarify port vs preferred_port behavior by adding allow_port_mismatch flag
* update all instances of default_vhosts to all_default_vhosts
* require port
* port should never be None in _get_default_vhost
* Remove unneeded sys import.
Once upon a time we needed this in some of these setup.py files because we were
using sys in the file, but we aren't anymore so let's remove the import.
* use setuptools instead of distutils
* Adds type checking for certbot-nginx
* First pass at type annotation in certbot-nginx
* Ensure linting is disabled for timing imports
* Makes container types specific per PR comments
* Removes unnecessary lint option
