Optional signal for cancelling the request. The driver is responsible for honoring it: it
passes the signal to the provider's SDK or HTTP call, so an aborted request is torn down
rather than left running. A driver that stops because the signal fired reports the failure
classified as Cancelled (see BuildCancellationErrorInfo), which is never failed over.
