[Improvement] Make `IcebergRestKerberosHiveCatalogIT` works in the deploy mode

### What would you like to be improved?

The IT for Spark to access Iceberg rest server with Kerberos Hive does not work in the deploy mode, we need to solve this problem.

### How should we improve?

_No response_

Start with the IcebergRestKerberosHiveCatalogIT integration test and its Spark deploy-mode configuration. Reproduce the failure in deploy mode, trace the Kerberos Hive catalog access path, and confirm that the integration test passes in that mode.
