Review Comment:
> these 2 hints are not suppose to be directly used by user.
You both may have already discussed this but not sure I follow this. At
least in the other PR, we want to create a hint and expose it to user.
Fair to say that if I want to add a new hint and expose it to the user, this
will have to be evolved / extended or there is a different plan ?
```
public static final HintStrategyTable PINOT_HINT_STRATEGY_TABLE =
HintStrategyTable.builder()
.hintStrategy(INTERNAL_AGG_INTERMEDIATE_STAGE,
HintPredicates.AGGREGATE)
.hintStrategy(INTERNAL_AGG_FINAL_STAGE, HintPredicates.AGGREGATE)
```
