Details
===
- add hintable option framework
- indicates the hint applicable node (`aggOptions`, `joinOptions` are
added for now)
- each hint support arbitrary k-v options (e.g.
`joinOptions(join_strategy='dynamic_broadcast', colocated_by_join_keys='true')`
- extensibility of hintable option framework:
- more applicable nodes can be added to `PinotHintOptions` class,
- generic k-v options support can also be added to the
`PinotHintOptions.<xxx>Options` sub-class
- specific k-v options support can be added by each Pinot optimizer rules
themselves individually
- also added the dynamic_broadcast hint and rel optimizer rule
- this helps execute queries similar to
([IN_SUBQUERY](https://docs.pinot.apache.org/users/user-guide-query/filtering-with-idset#in_subquery))
- also sanitized agg hint options and tests.
