clusternet hub can not create resource with apiversion that different from prioritized apiversion

[xrmzju]

• in k8s v1.22, autoscaling/v1 is prioritized for horizontalpodautoscalers

kubectl api-resources --api-group=autoscaling

This is a known issue that clusternet-hub will pick out preferred version or highest semantic version. In Kubernetes v1.22, autoscaling/v1 has the highest priority than autoscaling/v2beta2.
