Added Kafka metrics for CDS workers

Added counters to gather metrics on CDS Kafka workers.
This will enable us to get metrics on how many messages we consumer and produce to/from kafka.
For consumers we count how many messages we consume and how many failed ie. consumed but not able to be processed (parsing error).
For producers we count how many messages we produce and how many failed ie. failed to be pushed to the cluster (unavailable brokers, network error, ...).
Relocated metrics tag constants to BlueprintConstants so that they can be use by any CDS module.
If they make sense for other metrics then they should be shared.
