    [FLINK-5985] Report no task states for stateless tasks in checkpointing

    This PR fixes [FLINK-5985]. The solution is based on acknowledging `null` instead of some
empty SubtaskState to `CheckpointCoordinator#acknowledgeCheckpoint(...)`, so that no `TaskState`
is registered under the `JobVertexID` of a stateless task in the checkpoint.
