> Add a Kafka table source factory with JSON format support

> Similar to CSVTableSourceFactory a Kafka table source factory for JSON should 
> be added. This issue includes improving the existing JSON descriptor with 
> validation that can be used for other connectors as well. It is up for 
> discussion if we want to split the KafkaJsonTableSource into connector and 
> format such that we can reuse the format for other table sources as well.
