The completed status of the podgroup will be updated to the inqueue status

[wangyang0616]

What happened:
If the enqueue action is not configured, after the podgroup status is updated to Completed, it will be updated to the inqueue status soon.

What you expected to happen:
After the podgroup is updated to the Completed state, Volcano will not schedule the job unless the job status is updated externally

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:
Code logic see：

volcano/pkg/scheduler/actions/allocate/allocate.go

Lines 64 to 66 in e145aff

	if !conf.EnabledActionMap["enqueue"] {
	job.PodGroup.Status.Phase = scheduling.PodGroupInqueue
	} else {

• Kubernetes version (use kubectl version):
