Manually renew SSL

Exactly what it sounds like. Just a button on the admin or user interface to manually renew an SSL cert for a domain.
Sometimes when on-boarding new domains SSL just doesn't go right. I had a site that letsencrypt apparently decided not to add WWW as valid for the domain. And the wordpress site defaulted to WWW. Since there was no way to manually renew the SSL cert, I had to ask support to sort it our for me.

Could I have cloned the website to a subdomain of another domain, delete the domain, remake it, do a new SSL cert and then clone it back? sure....but that's a bit nuts. Let's make life easy with a renew button.
I would probably rate limit it internally though. Just to prevent people from spamming renew and then letsencrypt rate limits the domain from renewals. Realistically this isn't really a button that needs to be pressed almost ever. But when something in SSL breaks it will be a godsend to have.
