> Some MQTT use-cases involve clients which don't clean up their subscriptions. 
> In such situations the {{auto-delete-queues-delay}} and 
> {{auto-delete-queues-message-count}} address-settings can be used to clean up 
> the abandoned subscription queues. However, the MQTT session meta-data is 
> still present in memory and needs to be cleaned up as well.
