[POC/RFC] Authorization handler for ResourceController

I use `ResourceBundle` for all my new projects. And almost every time, I have to have to check special authorization for a given action and resource. 

The goal of this PR is to handle authorizations by doing something as simple as : 
```php
class MyResourceController extends ResourceController 
{
   public function checkEditAuthorization()
   {
       if (false === this->get('security.context')->isGranted('ROLE_TO_CHECK') {
            throw new AccessDeniedException();
       }
   }
}
```

Note : I did not test anything. This is just a POC, or a RFC.
