Review comment:
Add a setter function here instead of passed in from constructor, because
[`StreamGraph#getStateBackend()`](https://github.com/apache/flink/blob/f38106582e69765677ef8ebddece3a92641f6f22/flink-streaming-java/src/main/java/org/apache/flink/streaming/api/graph/StreamingJobGraphGenerator.java#L895)
may return null in `StreamingJobGraphGenerator#configureCheckpointing`
