Alternative way to implement auth

[tanguilp]

Hello!

First, thanks for your work on this great library 🥇

I've implemented auth in another way which, I think, is simpler that what is proposed with unplug:

scope "/metrics" do
  pipe_through :admin_auth

  get "/", PromEx.Plug, prom_ex_module: Clive.PromEx
end

Is there any problem with this approach? Otherwise I think this is what should be documented. I'd be happy to update the doc.

Cheers!

Sorry for the delay. Between running a business and writing 2 Elixir books at the moment my open source time has been cut down dramatically :/.

Definitely not an issue doing it this way. The Unplug example was just one simple way of solving the problem...but definitely not the only one. If you want to update the documentation to include your approach, I would not say no :).
