HAWKULAR-751 Avail Creator: server runs out of memory under heavy load
MetricReceiver performance enhancements
Under heavy load, this bean was a slow consumer and made the system run out of memory.
In order to consume messages faster:
- disable transaction support
- use a shared ObjectMapper
- navigate Json with Jackson API
- don't call the publisher if nothing to send

Avoid calling blocking APIs in the consumer thread.
The blocking call was a consequence of HAWKULAR-113. But it seems that without tx support,
asynchronous annotation works well.
