Description

Why This allows a grafana board on EventBus fatal errors

The admin would thus know he needs to go and analyse/reprocess/clean dead letter.

Modify dead-letter with a "Publisher failedEventCount()" method - and write unit tests for it.

Implement it with a counter for "Cassandra Event dead letter".

DOD: Test gauge size as part of deadLetter contract, all implementation should publish it. Add a grafana board for this.
