Send a Staged REST Request with a Text Body

Demonstrates Rest.SendReqStringBody, which sends a request whose text body (such as JSON) is supplied directly, then reads the response in separate steps.

Background. The staged request model separates sending from reading: a SendReq method transmits the request, ReadResponseHeader reads the status line and headers, and a ReadResp method reads the body. This gives fine control over large or streamed messages compared with the single-call full-request methods.
