Hi Ivan, nice job with this example.
I found another potential issue with the metrics in TomEE, If you remove
the `monotonic = true` from the @Counted annotation, then the format of the
endpoint: http://localhost:8080/rest-mp-metrics/metrics is no longer
Prometheus but JSON instead.
Without `monotonic = true`
{"application":{"message_counter":0},"vendor":{"startTime":1542679115312},"base":{"classloader.totalLoadedClass.count":8971,"thread.count":39,"classloader.currentLoadedClass.count":8971,"jvm.uptime":103050,"gc.PS
MarkSweep.count":2,"thread.max.count":39,"memory.committedHeap":369098752,"gc.PS
Scavenge.count":7,"cpu.availableProcessors":4,"thread.daemon.count":38,"classloader.totalUnloadedClass.count":8971,"memory.maxHeap":3817865216,"memory.usedHeap":69535960,"gc.PS
MarkSweep.time":141,"gc.PS Scavenge.time":103}}
With `monotonic = true`

This is not stated on the MP metrics spec. So I wonder if TomEE should
provide a set of properties to avoid these random behaviors.
