WorkerPool.spec.successfulPodsHistoryTTL

SuccessfulPodsHistoryTTL specifies the duration to keep successful Pods after they are created. When set, successful Pods that have been created for longer than this duration are removed. The TTL timer starts from Pod creation time for consistency with history limit ordering. Running pods are never affected by this TTL. When unset (nil), no time-based cleanup is performed for successful Pods. This works in combination with SuccessfulPodsHistoryLimit - pods are removed if they exceed EITHER limit.
