### Why are the changes needed?
The vanilla Spark neither support rolling nor expiration mechanism for `spark.kubernetes.file.upload.path`, if you use file system that does not support TTL, e.g. HDFS, additional cleanup mechanisms are needed to prevent the files in this directory from growing indefinitely.
This PR proposes to let `spark.kubernetes.file.upload.path` support placeholders `{{YEAR}}`, `{{MONTH}}` and `{{DAY}}` and introduce a switch `kyuubi.kubernetes.spark.autoCreateFileUploadPath.enabled` to let Kyuubi server create the directory with 777 permission automatically before submitting Spark application.
For example, the user can configure the below configurations in `kyuubi-defaults.conf` to enable monthly rolling support for `spark.kubernetes.file.upload.path`
```
kyuubi.kubernetes.spark.autoCreateFileUploadPath.enabled=true
spark.kubernetes.file.upload.path=hdfs://hadoop-cluster/spark-upload-{{YEAR}}{{MONTH}}
```
Note that: spark would create sub dir `s"spark-upload-${UUID.randomUUID()}"` under the `spark.kubernetes.file.upload.path` for each uploading, the administer still needs to clean up the staging directory periodically.
For example:
```
hdfs://hadoop-cluster/spark-upload-202412/spark-upload-f2b71340-dc1d-4940-89e2-c5fc31614eb4
hdfs://hadoop-cluster/spark-upload-202412/spark-upload-173a8653-4d3e-48c0-b8ab-b7f92ae582d6
hdfs://hadoop-cluster/spark-upload-202501/spark-upload-3b22710f-a4a0-40bb-a3a8-16e481038a63
```
Administer can safely delete the `hdfs://hadoop-cluster/spark-upload-202412` after 20250101
