Chrome should send cookieless request to WebAPK server.

WebAPK server only takes the user agent from the request sent from
Chrome, and ignores cookies. From security perspective, it is safer
to send request without any cookie. Therefore, we add flag to exlude
cookies from the request to the WebAPK server.
