Custom domains for ic0.app [Community Consideration]

The way it will work is that a developer can set their DNS name to point to the boundary nodes. Boundary nodes will generate an SSL certificate (through the letsencrypt DNS challenge) and maintain a mapping of name to canister so they know how to route traffic.

I believe this works because Firebase has the certificate. At first I tried this using a CNAME but ran into TLS issues and my domain name got flagged for phishing.
