      Description

      In order for load balancer to make better decision, we need to establish cost model for moving region(s).
      One factor would be the number of active scanners on a particular region.
      This count is easy to maintain at HRegion level. instantiateInternalScanner() can increment the counter and RegionScanner.close() would decrement the count.
