Description

There are different column stats aggregator instances for each different types, e.g., DateColumnStatsAggregator, LongColumnStatsAggregator, DoubleColumnStatsAggregator, etc. Much of the logic in those classes seems to be common or could be generalized and reused; we should move it into ColumnStatsAggregator parent class or a utility class.
