Review comment:
Why not call `getKey` and `getValue` to avoid code duplication? Is this to
be a little more efficient?

> Project: Apache Gobblin
> Issue Type: Improvement

> Reporter: Shirshanka Das

> Priority: Major

> The current Kafka writer uses the non-keyed API to produce to Kafka.
> This issue proposes to add support for keyed writes to Kafka.
> Constraints:
> * Minimal changes needed to existing pipeline configuration to add support
> for keyed writes to Kafka
> * Minimal changes to gobblin-core. Do not add general support for
> keyed-writers as part of this issue.
