## What changes were proposed in this pull request? The patch implements granular metrics around `KeyManagerImpl#sortDatanodes` method. The following metrics have been introduced: - **_sortDatanodesLatencyNs_**: `KeyManagerImpl#sortDatanodes` call latency in nanoseconds. - **_sortDatanodesSortByDistanceCostLatencyNs_**: `NetworkTopology#sortByDistanceCost` call latency in sortDatanodes. - **_sortDatanodesResolveNodeLocationLatencyNs_**: `KeyManagerImpl#resolveNodeLocation` latency in sortDatanodes (for non-datanode host reads). - **_numSortDatanodesCalls_**: Number of `KeyManagerImpl#sortDatanodes` calls. - **_numSortDatanodesNonDatanodeHostReads_**: Number of non-datanodes host reads in sortDatanodes (number of `KeyManagerImpl#getOtherNode` calls). ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-10357 ## How was this patch tested? The metrics have been tested manually on a cluster with the Ozone services running. -- This is an automated message from the Apache Git Service.
