Resolve podgroup residual

[HDJZX]

background

Lack of external modules to manage PodGroup status based on workload status, making Volcano unable to perceive the lifecycle of upper level workloads (success/failure/pause/termination/scaling, etc.) and unable to manage PodGroup correctly. The following scenario will appear: - a. In scenarios where tasks (such as Pod/Job) run successfully/fail, the corresponding PodGroup remains and occupies the queue quota. - b. In scenarios where tasks (such as Deployment/StatefulSet) are scaled down to 0, the corresponding PodGroup remains and occupies the queue quota

Solution ideas

• When pod is in its final state:succeed、failed, clear the podgroup corresponding to pod。If pod has a controller owner reference, the check will be skipped
• When the number of statefulset replicas is 0, clear the podgroup corresponding to the statefulset
• When the job is in a paused state, clear the podgroup corresponding to the job (support for job pause operation is required)
