Description

1. duplicated condition update with Unschedulable and Scheduled, just retain one Scheduled is enough.
2. and add an extended condition to express the Unenqueueable event.
3. every pg will record a Unschedulable type event fisrt no matter whether resources are enough and then schedule successfully.

Steps to reproduce the issue

2. Execute "kubectl describe pg xxx", will see podgroup contains conditions that unschedulable and scheduled.
   3.Execute “kubectl get events --sort-by='.metadata.creationTimestamp'”, will see warning event "job xxx unscheduler, reasion:...."

expected:

1. Only one condition is used to describe podgroup scheduling.
2. No unscheduable warning event occurs in the pod group that is normally scheduled.

Maybe we can add a new condition type named Unenqueueable instead of a reason attached to Unschedulable.
