Description

Based on design, when VM worker job cleanup thread runs, it should only expunge those vm work jobs that are completed more than one hour ago. This is to prevent some Db constraint error in expunging these jobs since there are still reference to the worker job in async_job_map table. Also on some racing condition, we will encounter NPE due to removal of such jobs too quickly.
