Feature/store configuraton json idented (#328)

* messing around with benchmark.net.seems Ocelot adds about 2ms to a request..lets make this less? :)

* #326 store json indented so it looks nice :P

 Ocelot will now register all the necessary services when it starts up and if you have the json above will register itself with

 When Ocelot asks for a given service it is retrieved from memory so performance is not a big problem. Please note that this code
