Description

We should test manually changes introduced in FLINK-25276 & FLINK-25154

Proposal:
Take canonical savepoint/native savepoint/externalised checkpoint (with RocksDB), and perform claim (1)/no claim (2) recoveries, and verify that in:

1. after a couple of checkpoints claimed files have been cleaned up
2. that after a single successful checkpoint, you can remove the start up files and failover the job without any errors.
3. take a native, incremental RocksDB savepoint, move to a different directory, restore from it

• causes: FLINK-26353 "flink stop --help" does not list "--type" option
• causes: FLINK-26354 "-restoreMode" should be "--restoreMode" and should have a shorthand
