CLI: create a CLI for more interactive and language agnostic setup

[odeke-em]

Advised offline by a friend(who knows themselves), a great idea is to make the tool an interactive CLI that cuts out the need for folks to know Go; if they just want HTTPS frontends, the tool should be right for them and after passing in their desired configs, should be able to have a binary generated for them or Docker image or whatever -- it should just work!
