Using external HTTPS / TLS service is broken

[joepio]

Although Atomic-server has its own HTTPS logic, it should also work with external TLS / SSL providers. Currently, passsing --https is responsible for setting the base_url.

How should I fix this?

Create custom-server-address option that replaces domain

Seems easy to implement, but adds some redundancy in config variables, since both will be needed

Have an --https-external and --http-external flag

Two flags.. yuck

Have an --external-server flag

toggle this and it will not add ports to the base URL. But that still sucks, because we'll still need to know if we're using HTTPS or not.
