onSchedule():
- get response information from broker

onTrigger():
- subscribe to response topic
- publish with correlation data and response topic set
- wait for response

Questions:
- what should happen to incoming flow files? replace content with response or create new ones instead?
- how should response topic be set? concatenate to response information?

Further ideas:
- also implement for Last Will in CONNECT packet
