Description

KIP-791: https://cwiki.apache.org/confluence/display/KAFKA/KIP-791%3A+Add+Record+Metadata+to+State+Store+Context

In order for state stores to provide stronger consistency in the future (e.g., RYW consistency) they need to be able to collect record metadata (e.g., offset information).

Today, we already make record metadata available in the AbstractProcessContext (recordMetadata()), but the call is not currently exposed through the StateStoreContext interface that is used by the state store. 

The task of this ticket is to expose recordMetadata in the StateStoreContext.
