Counter (Apache BookKeeper :: Parent 4.18.0-SNAPSHOT API)

All Known Implementing Classes:

LongAdderCounter, NullStatsLogger.NullCounter, OtelCounter, ThreadScopedLongAdderCounter
```
public interface Counter
```
Simple stats that require only increment and decrement functions on a Long. Metrics like the number of topics, persist queue size etc. should use this.
