Commented Issue: Convert MessageDetail in HttpError to ODataInnerError [703]

ODataError doesn’t support custom error, but it can have ODataInnerError, which can contain a nested InnerError, message, stack trace and type name.<br /><br />We should be able to use ODataInnerError.Message to include MessageDetail in HttpError.<br />
