Dynamic DNS zones

An option to allow RFC 2136 DNS updates for domains handled by Virtualmin would be nice. In addition to providing dynamic DNS, this would allow users to take advantage of certbots dns_rfc2136 plugin to obtain SSL certificates. This would negate the need for a "virtualmin plugin" for certbot.



Virtualmin already has built-in support for DNS validation with Let's Encrypt, so I don't see why this is needed?
