http: allow sending message body for DELETE request

Sending entity within DELETE is not forbidden by RFC 7231, see section
4.3.5. DELETE:
> A payload within a DELETE request message has no defined semantics;
> sending a payload body on a DELETE request might cause some existing
> implementations to reject the request.
