> After YARN-3635/YARN-6689, PlacementRule becomes a common interface which can be used
by scheduler and can be dynamically updated by scheduler according to configs. There're some
other works. 
> - There's no way to initialize PlacementRule.
> - No example of PlacementRule except the user-group mapping one.
> This JIRA is targeted to refine PlacementRule interfaces and add another PlacementRule
example.
