## Description 
This is one of many PRs to implement Leader Scoring & Leader Schedule
feature for Mysticeti.
- [Design
Doc](https://www.notion.so/mystenlabs/Leader-Schedule-Scoring-538c65cb370b4644944a94485efc4979?pvs=4)
- [Prototype PR](https://github.com/MystenLabs/sui/pull/16975)

Notes:
- `LeaderSwapTable` & `ReputationScores` are mostly the same from the NW
implementation
- Kept the `Authority` & `ReputationScores` info in `LeaderSwapTable`
mostly for debugging purposes. It is not required functionally
