----------------------------------------
    Attachment: SOLR-9805.patch

Patch which applies to the features/metrics branch. We add all jvm metric sets from metrics-jvm library to a shared metric registry named "/jvm". Following are the metrics collected:
{code}

    }
  },
  "counters" : { },
  "histograms" : { },
  "meters" : { },
  "timers" : { }
}
{code}

Since the /admin/metrics endpoint is constrained to show only one metric registry at a time, it does not show the JVM metrics. I'll fix the metrics API in a separate issue.
