This is a follow up to #11012 ## What? For incoming MQTT messages, always set the `durable` message container annotation. ## Why? Even though defaulting to `durable=true` when no durable annotation is set, as prior to this commit, is good enough, explicitly setting the durable annotation makes the code a bit more future proof and maintainable going forward in 4.0 where we will rely more on the durable annotation because AMQP 1.0 message headers will be omitted in classic and quorum queues (see #10964) For MQTT messages, it's important to know whether the message was published with QoS 0 or QoS 1 because it affects the QoS for the MQTT message that will delivered to the MQTT subscriber. The performance impact of always setting the durable annotation is negligible. (cherry picked from commit e576dd7)
