Review comment:
Well, yes and no. This PR is only documenting the status quo of the
current (but "old") API.
There is
https://cwiki.apache.org/confluence/display/KAFKA/KIP-478+-+Strongly+typed+Processor+API
that introduces a new API, including:
```
interface ProcessorContext<K, V> { // this is a new class with same name but
located in different/new package
Optional<RecordMetadata> recordMetadata();
}
```
The KIP is not fully implemented yet, and thus the current API is not yet
deprecated.
