Fix calculation issue for extension resource in volcano.

[TommyLike]

Use original ResourceList sum up logic to avoid resource amplify issue.

minAvailableTasksRes.Add(kbapi.NewResource(c.Resources.Requests))

The code above should not be used outside of kube-batch, since when converting back, the resource would be amplified with 1000 times. see here

It's better to make Convert2K8sResource and NewResource align with each other. BTW, please rename Convert2K8sResource to ToResourceList.

@k82cn I agree, but for your suggestion, it's the matter of kube-batch's, we don't need to convert it into kube-batch type and then convert it back here.

[k82cn]

we should not duplicate the code; we maintain both repo.

Which are duplicated?

please help to rename Convert2K8sResource to ToResourceList and make sure them align.

They are different logics, one for the kube batch resource and the other for kubernetes resource. And within this update method Convert2K8sResource is not being used anymore

[k82cn]

Convert2K8sResource is also a bug to me, please update kube-batch to make them align.
