Add digested system metrics to SystemMetrics demux parser
---------------------------------------------------------

                 Key: CHUKWA-571
                 URL: https://issues.apache.org/jira/browse/CHUKWA-571
             Project: Chukwa
          Issue Type: New Feature
          Components: MR Data Processors
         Environment: Java 6, Mac OS X 10.6
            Reporter: Eric Yang
            Assignee: Eric Yang


For now, the system metrics demux parser are storing raw metrics.  Each system components
are measured independently.  It would be nice to make a summary grouping for cpu, disk, network.
 Instead of storing cpu:combined.0 ... cpu:combined.8, for 8 cpu cores in the system, it would
be nice to have a average number for all cpus combined.  The digested metrics are easier to
aggregate at cluster level.
