WebGUI::Session::Http should go away (#11647)
Move logic out of WebGUI::Session::HTTP and into WebGUI::Session::Response / ::Request; deprecate more functions; change references in core to use $session->response instead; fix tests that broke because of the change but not one that merely generate the deprecated warning because I want to know that the proxying of depricated methods is working. These can be changed later.
