Review comment:
This makes sense, however, KafkaCheckpointManagerFactory already adheres to
these configs when creating the spec.
Please see KafkaCheckpointManagerFactory Line 52-55
```val checkpointSpec =
KafkaStreamSpec.fromSpec(StreamSpec.createCheckpointStreamSpec(checkpointTopic,
checkpointSystemName))
.copyWithReplicationFactor(kafkaConfig.getCheckpointReplicationFactor.get.toInt)
.copyWithProperties(kafkaConfig.getCheckpointTopicProperties)```
