Description
Provide a LAZY_PERSISTENT DeliveryMode that allows the broker to acknowledge the producer before the message has been sync (fsync()) to disk. Allows for brokers to incorporate async writes and write caching techniques for performance while providing for better-than-non-persistent reliability.
See: Kafka, ActiveMQ async() write etc.

Research direction
Start with the DeliveryMode API entry point and trace how brokers acknowledge producers and synchronize messages with fsync(). Compare the requested semantics with the Kafka and ActiveMQ async-write examples named in the issue; done means a defined LAZY_PERSISTENT mode with agreed broker behavior and coverage for its reliability guarantees.
