[FLINK-34015] fix setting execution.savepoint.ignore-unclaimed-state …
…does not take effect when passing this parameter by dynamic properties
What is the purpose of the change
fix setting execution.savepoint.ignore-unclaimed-state does not take effect when passing this parameter by dynamic properties.
(For example: This pull request makes task deployment go through the blob server, rather than through RPC. That way we avoid re-transferring them on each deployment (during recovery).)
Brief change log
when combining the savepoint restore setting from cli options and dynamic properties, check whether the cli option is none(), if true, just NOT setting it to the configuration.
(for example:)
- The TaskInfo is stored in the blob store on job creation time as a persistent artifact
- Deployments RPC transmits only the blob storage reference
- TaskManagers retrieve the TaskInfo from the blob cache

(or)
This change added tests and can be verified as follows:
added unit test: org.apache.flink.client.cli.CliFrontendITCase#configurationRestoreMode
(example:)
- Added integration tests for end-to-end deployment with large payloads (100MB)
- Extended integration test for recovery after master (JobManager) failure
- Added test that validates that TaskInfo is transferred only once across recoveries
- Manually verified the change by running a 4 node cluster with 2 JobManagers and 4 TaskManagers, a stateful streaming program, and killing one JobManager and two TaskManagers during the execution, verifying that recovery happens correctly.
