hack in a controller that requests from another

WIP/HAX

@linedotstar - threw together a "proxies controller" that makes requests to other controllers via Faraday::Adapter::Rack, I'll add in some comments about various issues... Main one seems to be that Rack::Lock had to be removed but I have some ideas around that.

LMK what you think
just for shits i adjusted this spec to use Faraday::Adapter::Rack instead, but it's not a very good test of the feature because it's from outside the app, not within the app, so there's no multiple request/rack::lock bs to deal with.
