Description of PR

HADOOP-19992

The OSS SDK does not retry CompleteMultipartUpload by default, so QpsLimitExceeded can fail multipart uploads and copies even when fs.oss.attempts.maximum is configured.

Share completion retry logic between uploads and copies, retrying only QpsLimitExceeded with Hadoop's exponential backoff and jitter. Add fs.oss.multipart.complete.retry.limit (default: 3, range: 0–10) and fs.oss.multipart.complete.retry.interval (default: 500ms), with each delay capped at 10s. Document the settings and extend the existing test class without adding dependencies.

How was this patch tested?

• Compiled the changed Java sources and ran TestAliyunOSSFileSystemStore using a standalone JUnit launcher with OSS SDK 3.18.1 and locally cached Hadoop dependencies: 4 unit tests passed; 3 live OSS tests were skipped because credentials were unavailable.
• Covered retry success/exhaustion, disabled retries, backoff and delay cap, configuration validation, non-retryable failures, interruption, and multipart copy completion/abort behavior.
• git diff --check passed. Full Maven validation was not completed because required build plugins and dependencies were unavailable locally.
• Live OSS integration tests have not been run; no endpoint was used.

For code changes:

• Does the title of this PR start with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
• Object storage: Have the integration tests been executed and the endpoint
  declared according to the connector-specific documentation? Note: Automated CI
  testing doesn't cover all cases so manual testing with cloud storage is still
  required.
• If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0? N/A: no new dependencies.
• If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files? N/A: no licensing changes.
