Let's Encrypt failing is port 80 not mapped -> Show warning or error quicker

[dewey]

Description of feature

When renewing a certificate the LE renewal is failing if there's no port 80 mapped to the app, adding the port 80 fixed the issue (dokku ports:add <app> http:80:3000). It was suggested on IRC to open a ticket to improve this behavior.

Please file a ticket for the port mapping issue, we can just error out immediately if a http:80 port mapping is not found
