Description

Includes write ops and latencies at coordinator per column family.

Relevant discussion in dev mailing list - https://lists.apache.org/thread.html/f68f694b13b670a1fa28fa75620304603fc89e94ec515933199f4c37@%3Cdev.cassandra.apache.org%3E

Below are a few advantages of having such metric

• Ability to identify specific column family that coordinator writes are slow to
• Also useful in a multi-tenant cluster, where different column families are owned by different teams
