Description

Partition Pruner has logic reusable like

1. walk through operator tree
2. walk through operation tree
3. create pruning predicate

The first candidate is list bucketing pruner.

Some consideration:
1. refactor for general use case not just list bucketing
2. avoid over-refactor by focusing on pieces targeted for reuse
