Description

Currently, Router's operations are not well recorded. It would be good to have a similar metrics as "Hadoop:service=NameNode,name=NameNodeActivity" for NameNode, which shows the count for each operations.

Besides, some operations are invoked concurrently in Routers, know the counts for concurrent operations would help us better knowing about the cluster's state.

This ticket is to add normal operation metrics and concurrent operation metrics for Router.
