At the moment it's only possible to configure a storeLimit per broker.
In some cases, you want to set an upper bound for an individual queue, to guarantee that there will be storage available for other queues.
For example, consider a setup with a request queue, and a response queue, where both request and response messages are huge.
In that situation, we want to set an overall store limit, to prevent flooding the filesystem.
At the same time, we don't want to allow the request queue to consume 100% of the broker store.
For example, we'd like to define:
total broker store limit: 20 GB
queue "request_queue" store limit: 15 GB
queue "response_queue" store limit: 5 GB
