Support managed and scheduled single pods with podgroup, specify podgroup name and minresource manually

[zbbkeepgoing]

What would you like to be added:

• Support specify podgroup name and minresources manually

Why is this needed:

• If we use spark client model to submit spark job in k8s with volcano scheduler. hope all executors can be managed and scheduled through podgroup.

• Hope some single pods(not a denpendent pod) can be managed and scheduled through podgroup with volcano.
