Amnon Heiman e2cdc95b81 APIHistogram: Moving the histogram data collection to the API ... This patch replace the Histogram data and statistic calculation from the JMX proxy to the API. This way the count, sum, min, max variance and square sum are calculated always on the server. When an update is perform, the API would return the statistic with a sample of the last n elements as a sample. This implementation insure that the counters are correct. The implementation also allows to set the minimal update interval. The implementation adds a mutable getter for each of the parameters so they could be set to their new value.
