Symptoms: Error message about a Kafka consumer allocated but not closed appears in our log messages
Cause: The MetadataResouceUtil has a Kafka checkpoint manager that is never closed in our code. A LifeCycleAwareConsumer sees this and complains about it.
Fix:: Add a stop in MetadataResourceUtil that will close the checkpoint manager in it. Then have MetadataResourceUtil.stop called everywhere it's used when the job is stopped
Tests: Any job that uses ProcessJob or PassthroughJobCoordinator will see errors in the log files about a Kafka consumer allocated but not closed. With this fix in, that error shouldn't appear
