> HDFS-10917 added various peer performance metrics on individual DataNode. These metrics
should be reported to NameNode as part of heart beat messages. In addition, NameNode should
maintain the corresponding metrics but in a way of aggregation, and therefore friendly consumable
by DataNode self-healing actions afterwards.
