This is a big part of #7214. It removes all references to TLS-SNI-01 outside of acme (and pytest.ini). Those changes will come in a subsequent PR. I thought this one was getting big enough.
* Remove references to TLS-SNI-01 in Apache plugin
* Remove references to TLS-SNI-01 from certbot-nginx
* Remove references to TLS-SNI from Certbot.
* Remove TLS-SNI reference from docs
* add certbot changelog
* Clarify test behavior
