0006318: add health system dumping of threads when there is an anomaly in request time

Description

(rep by Mitsuo)

Seeing the following anomalies in the logs:

    [19-10-03 13:13:00.003] {resin-997} AnomalyAnalyzer Resin|Http|Request Time WARNING
                        5019.000 sample is 6428.23% of 78.077 avg, 15.708 std deviations (std=314.555, n=473.0)
    [19-10-03 13:15:00.003] {resin-943} AnomalyAnalyzer Resin|Http|Request Time WARNING
                        5942.000 sample is 6544.87% of 90.789 avg, 14.151 std deviations (std=413.489, n=475.0)

To dump the threads on an http request time anomaly:

  <health:AnomalyAnalyzer>
    <meter>Resin|Http|Request Time</meter>
    <health-event>caucho.http.anomaly.request-time</health-event>
    <min-deviation>4</min-deviation>
  </health:AnomalyAnalyzer>

  <health:DumpThreads>
    <health:Or>
      <health:IfHealthWarning healthCheck="${cpuHealthCheck}" time="2m"/>
      <health:IfHealthEvent regexp="caucho.thread"/>
      <health:IfHealthEvent regexp="caucho.http"/>
    </health:Or>
