Description

Currently when we have MergeNormalizationPlan we do a force merge in execute method

// code placeholder
admin.mergeRegions(firstRegion.getEncodedNameAsBytes(),
  secondRegion.getEncodedNameAsBytes(), true);

Since we do not expect these regions to be non adjacent it is better to not force merge and be on safe side.
