TAJO-1343: Improve the memory usage of physical executors
Here are some highlights.
* Cleanup duplicated tuple creation.
* To maintain tuple creation easily, I've added three new data structures,
called TupleMap, TupleList, and TupleSet. They automatically clone tuples
whenever a new item is added.
* Fix a bug in WindowAggregation and two wrong tests.
* Fix a bug in timezone.
I will conduct some tests and share the results.
