// your delivery stream is created, call DescribeDeliveryStream to see whether
// the delivery stream is ACTIVE and therefore ready for data to be sent to
// it.
//
// If the status of a delivery stream is CREATING_FAILED, this status doesn't
// change, and you can't invoke CreateDeliveryStream again on it. However, you
// can invoke the DeleteDeliveryStream operation to delete it. If the status
// is DELETING_FAILED, you can force deletion by invoking DeleteDeliveryStream
// again but with DeleteDeliveryStreamInput$AllowForceDelete set to true.
