KAFKA-3229 ensure that root statestore is registered with
ProcessorStateManager
Pass through the root StateStore in the init method so the inner StateStore
can register that object.

> Key: KAFKA-3229
> URL: https://issues.apache.org/jira/browse/KAFKA-3229
> Project: Kafka
> Issue Type: Bug
> Components: kafka streams
> Affects Versions: 0.9.1.0
> Environment: MacOS El Capitan
> Reporter: Tom Dearman
> Fix For: 0.9.1.0
>
>
> When the hierarchy of nested StateStores are created, init is called on the
> root store, but parent StateStores such as MeteredKeyValueStore just call
> the contained StateStore until a store such as MemoryStore calls
> ProcessorContext.register, but it passes 'this' to the method so only that
> inner state store (MemoryStore in this case) is registered with
> ProcessorStateManager. As state is added to the store none of the parent
> stores code will be called, metering, or even StoreChangeLogger to put the
> state on the kafka topic.
