pending pod cannot trigger autoscaler scale up

[bibibox]

Description

in the #3498 , we support updating NominatedNodeName for pipelined task
now we met one situation, the kube-scheduler and volcano's behaviour is not same

Steps to reproduce the issue

1. create a cluster with one 1C1G node
2. create a pod A, which request 1C1G, with the preStop command sleep 600
3. after the pod A is running, delete it. the pod A will be terminating in 10 minutes
4. create a pod B with request 1C1G, and it will be pending

Describe the results you received and expected

expected:
same as the kube-schduler, mark the pending pod as unschedulable and will not update its nominatedNodeName field

received:
mark the pending pod as unschedulable and update its nominatedNodeName field
