CLOUD: Add UploadFileClientHandler Now Client reads the first headers block, then LocalWebserver decides which Handler to use. In case of "/upload", UploadFileHandler is used. But now it only knows the "path" parameter. If that's valid, actual UploadFileClientHandler is created, which reads the contents of the request and, when finds there an "upload_file" field, starts saving it in the directory specified by "path". With that we don't need temp files approach from Reader class.
