Add a metrics for tracking the number of reported corrupt replicas
------------------------------------------------------------------

                 Key: HDFS-1537
                 URL: https://issues.apache.org/jira/browse/HDFS-1537
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: Hairong Kuang
            Assignee: Hairong Kuang
             Fix For: 0.23.0


We have a cluster, some of its datanodes' disks are corrupt. But it tooks us a few days to
be aware of the problem. Adding a metrics that keeps track of the number of reported corrupt
replicas would allow us to have an alert when unusual number of corrupt replicas are reported.
