title: Multiple root route for FOSRestBundle
body: <p>I'm using the FOSRestBundle and I can't find how to have two different endpoint, one for the template rendering (html/twig, <code>/app</code> for example) and another one for the serialization (json, <code>/api</code> for example). Is it possible ? The documentation for <a href="https://symfony.com/doc/master/bundles/FOSRestBundle/5-automatic-route-generation_single-restful-controller.html" rel="nofollow noreferrer">FOSRestBundle Automatic Route generation</a>, does not indicate any of this.</p>
  
  <p>Using Symfony 3 and FOSRestBundle 2.x</p>
