### What is the purpose of the change Create `KryoSerializer` for `SequenceNumber` class explicitly to allow disabling of Generic Types via disableGenericTypes() call. ### Brief change log 1. Create KinesisStateUtil class with static method `createShardsStateSerializer` that explicitly assigns `KryoSerializer` to `SequenceNumber` class and use this method to initialize state 2. Create unit test that checks for compatibility of previous `TypeInformation` based serializer and explicitly created `KryoSerializer` 3.
