max_ack_pending

Hot Reloadable
`max_pending`, `max_inflight`This is the amount of QoS 1 messages the server can send to
a subscription without receiving any PUBACK for those messages.
The valid range is [0..65535].
The total of subscriptions' max_ack_pending on a given session cannot
exceed 65535. Attempting to create a subscription that would bring
the total above the limit would result in the server returning 0x80
in the SUBACK for this subscription.
Due to how the NATS Server handles the MQTT # wildcard, each
subscription ending with # will use 2 times the max_ack_pending
value. Note that changes to this option is applied only to new
subscriptions.
