    Description

      The goal of this task is to update HashAggStage and HashJoinStage so that HashAggStage's group-bys is collation-aware and so that HashJoinStage's mechanism for matching inner keys and outer keys is collation-aware.

      This will involve adding a slot to each classes constructor so that a collation can be passed in, as well as updating how the relevant hash table structures to be collation-aware.
