The delete, create and update actions return a RedirectResponse,  we lost some advantages of the `FosRestBundle`. 
+ For a deletion, if you want to send a response with empty body (see empty_content), it is impossible to configure the HTTP code returned.
+ For a update, I got a infinite redirection loop when I tried to update a resource using the PUT method. Moreover, if your client is not a browser, it is possible that it does not support redirect response.

I know that some methods has a lot of return has a lot of return, some developer does not like it but I have not problem with it. I need it ASAP for a project so I am here if you want to talk about this !

Should be more strict IMO to reduce lookups: `$request->attributes->get('_route')`.
