Merging your PR fixed the exactly-once guarantees @StephanEwen , great!
I also added an extra test for Partitioned states.
Do you think it is okay to leave the StreamCheckpointingITCase how I
modified it? Now it tests all the different checkpointing mechanisms together.
If you add a test for the Checkpointed interface itself, this should be good.

> Partitioned states are currently stored per-key in statehandles. This is
> alright for in-memory storage but is very inefficient for HDFS.
> The logic behind the current mechanism is that this approach provides a way
> to repartition a state without fetching the data from the external storage
> and only manipulating handles.
> We should come up with a solution that can achieve both.
