Interface: KyooJobNack()
Shape of the job negative acknowledgment function.
Remarks
In amqp, to re-enqueue the job at the end of the queue, we simply nack() and re-add it to the end of the queue. in bullmq, we use lifo to re-enqueue at the beginning of the queue. in sqs, to re-enqueue the job at the end of the queue, we simply delete the message and re-add it to the end of the queue.
Due to limitations with amqp, we cannot requeue a job at the beginning of the queue if we also need to honor the maxAttempts. In this case, we will requeue the job at the end of the queue.
