Review comment:
Copied my explanation from the Jira ticket why these classes are moved
to the package named this way:
If we do not move SubtaskCheckpointCoordinator(Impl), I think
`org.apache.flink.streaming.runtime.checkpointing` is a good choice.
But if we want to move SubtaskCheckpointCoordinator(Impl) together with the
above seven classes, I would lean to
`org.apache.flink.streaming.runtime.tasks.checkpointing`.
I think it is a good idea to put all checkpointing related classes
altogether, so I prefer
`org.apache.flink.streaming.runtime.tasks.checkpointing` as a result.
