To be merged once #5391 is in.

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 call latency in sortDatanodes (for non-datanode host reads).
• numSortDatanodesCalls: Number of KeyManagerImpl#sortDatanodes calls.
• numSortDatanodesNonDatanodeHostReads: Number of non-datanode host reads in sortDatanodes (number of KeyManagerImpl#getOtherNode calls).
