We have supported upsert format in kafka sink, but not yet in kafka source. For completeness, we should support that.

We can refer to flink's doc for the spec: https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/connectors/table/upsert-kafka/. In short, the spec is:

Use kafka message key as the primary key.
Use null in kafka message value to denote deletion on primary key.
