      Removes per-region level (get size, get time, scan size and scan time histogram) metrics that was exposed before. Per-region histogram metrics with 1000+ regions causes millions of objects to be allocated on heap. The patch introduces getCount and scanCount as counters rather than histograms. Other per-region level metrics are kept as they are.
