    @JPercivall Thanks for your time to review.
    
    I've looked at every existing Processors, Reporting tasks, and Controller 
services, but couldn't find other component needing external state management 
from NiFi.
    
    If you know particular component should implement this, please let me know.

> Inherently by the nature of a given processor it may involve state managed by 
> itself (using nifi state management), or can be managed by some external 
> service it interacts with (kafka's offset), and theoretically some might have 
> both going on. With the new state management, we're giving users a way to 
> reset state managed by nifi for a given processor. But it doesnt apply to 
> those processors who have external state.
> we should consider offering a way to reset state that allows a processor to 
> call out to whatever external store it impacts
