[Improvement] Add build-in jobs in Gravitino for table maintenance

### What would you like to be improved?

In the next version, we will add the table maintenance support for Iceberg tables. With this, we need to add some build-in job template and job artifacts in Gravitino.

### How should we improve?

_No response_

The issue names no files, tests, or entry points. First clarify the planned Iceberg table-maintenance support and the required built-in job templates and artifacts, then locate the relevant Gravitino job and Iceberg integration areas. Done means the agreed templates and artifacts are added and validated by the applicable project tests.
