[Feature][Zeta] Support automatic delete of completed task log files

Current, zeta support creating log files for each job, #7712

But because the logging framework cannot get the job status, it cannot automatically delete completed job log files.

Therefore, we can add a scheduled task to automatically delete the completed job logs.

Requirements:

Check regularly every day, use corn expression configuration, users can change the configuration, and it is executed every night by default
The log file can no longer find the unfinished job status (running/savepoint)
The log file has not been updated for 30 days, and users can change the configuration
