------------------------------------

No unit test included because this is web UI.  Tested it manually.

> HADOOP-7144 added JMXJsonServlet into Common.  It gives the capability to query statistics
and metrics exposed via JMX to be queried through HTTP.  We adopt this into HDFS.  This provides
the alternative solution to HDFS-1874.
