> Using the new Processor API introduced with KIP-820 when adding a state store to the Processor when executing `context().getStore("store-name")` always returns `null` as the store is not in the `stores` `HashMap` in the `ProcessorStateManager`.  This occurs even when using the `ConnectedStoreProvider.stores()` method
> I've confirmed the store is associated with the processor by viewing the `Topology` description.   
> From some initial triage, it looks like the store is never registered.
