I think it's OK that we don't change the format version (e.g. to v2) when
we change the serialization format in a snapshot version right? Since 1.1 the
version was already updated, which is fine.

> Restoring the HeapKeyedStateBackend is broken in case that parallelism is
> reduced. The restore method is overwriting previously restored state.
> We should also add scale-in testing to the RescalingITCase.
