Provide a general configuration to producers/consumers on Controller

Would be nice if we could save our developers time providing a way to configure general producers/consumers like sblanc suggested:

route().
.defaultProduces(JSP, JSON);
.defaultConsumes(JSP, JSON);

In this way users don't need to specify:

route()
.from("/delorean").roles("admin")
.on(RequestMethod.GET)
.to(Home.class).anotherPage();

But they can if it's necessary
