CLOSES: #1840
Start adding java ETL examples, starting with kafka etl.
We've had a few requests to start providing Java examples rather than Python due to type safety.
I've also started to add these to metadata-ingestion-examples to make it clearer these are *examples*. They can be used directly or as a basis for other things.
As we port to Java we'll move examples to contrib.
