Description

Some of our example bundle additional dependencies (like kafka). The example jars (that are deployed to maven central and included in flink-dist) should have proper licensing.
Otherwise we would have to disable deployment of these jars, and keep the flink-dist NOTICE file in sync with example dependencies manually.

One way to do this would be to add a separate module for each jar, or at the very least for those example that bundle dependencies.
