Document custom auth plugins

[nettnikl]

Is your feature request related to a problem? Please describe.
I'm trying to setup an authentication to happen before any request is processed. I think subclassing proxy.http.proxy.auth.AuthPlugin and loading it using --auth-plugin is the way to go here (loading it works actually, it just seems to never get called).
However i cannot even seem to get the basic auth (using the --basic-auth flag) to work for the reverse proxy.

Describe the solution you'd like
Some rudimentary documentation about how to implement - and activate! - my own auth plugin for a reverse proxy.

Describe alternatives you've considered
Add an example or tutorial

Thank you @nettnikl for bringing this to attention. I'll try add some clarity by updating docs and examples. Best

Revisiting this today. jFYI, reverse proxy doesn't support any sort of auth yet. Good point. I have created #1258 to track it separately

I'll close this down after adding documentation for auth plugin setup. Now that I read your ticket again, I understand you are probably looking for auth within reverse proxy, which is officially not implemented yet.
