Description

All Metric instance implement the Counting interface which exposes the count for underlying metrics

1. Counter - Counter value
2. Meter - Sum of all mark calls
3. Timer - Number of times timer is invoked
4. Histrogram - Number of times timer is invoked

This would avoid maintaining a duplicate sum variable for say maintaining the sum of all data upload recorded in a meter
