### What changes were proposed in this pull request? This PR aims to add `StorageLevel.DISK_ONLY_3` as a built-in `StorageLevel`. ### Why are the changes needed? In a YARN cluster, HDFS uaually provides storages with replication factor 3. So, we can save the result to HDFS to get `StorageLevel.DISK_ONLY_3` technically. However, disaggregate clusters or clusters without storage services are rising. Previously, in that situation, the users were able to use similar `MEMORY_AND_DISK_2` or a user-created `StorageLevel`. This PR aims to support those use cases officially for better UX. ### Does this PR introduce _any_ user-facing change? Yes. This provides a new built-in option. ### How was this patch tested? Pass the GitHub Action or Jenkins with the revised test cases. Closes #29331 from dongjoon-hyun/SPARK-32517.
