Messages delivered by RabbitMQ to consumers can be acknowledged automatically
(as soon as they are sent out) or manually using IModel#BasicAck.
You decide which mode to use. Unacknowledged messages are delivered but
not yet acknowledged. If the consumer(s) processing them fails, the messages
will be requeued.
“Ready” messages are not delivered and simply sitting in a queue.
Total = ready + unacknowledged.
