Related: #3019 Motivation: We have multiple (Full)HttpRequest/Response implementations and only some of them implements toString() properly. Modifications: - Add the reusable string converter for HttpMessages to HttpMessageUtil - Implement toString() of (Full)HttpRequest/Response implementations properly using HttpMessageUtil Result: Prettier string representation is returned by HttpMessage implementations.
