Description

Test for  https://issues.apache.org/jira/browse/FLINK-22684:

1. configure the external checkpoint address (storage)
2. enable unaligned checkpoint always (not the default aligned or alternative)
3. wait for the checkpoint then stop the job
4. restore from the last checkpoint - it should be restored on the last state(optional step)
5. set the `execution.checkpointing.recover-without-channel-state.checkpoint-id` to the last checkpoint
6. restore from the last checkpoint - in-flight data would be ignored so it would be restored a little less data than expected in the usual case.
