How to upgrade kfserving in kubeflow1.2

/kind bug

I try to upgrade kfserving from v0.4.0 to 0.5.0

1. I delete kfserving configure from kfctl_istio_dex.v1.2.0.yaml and update
2. I deploy kfserving0.5 by wget kfserving yaml
3. I entry my notebook and install kfserving==0.5.0
4. I execute this code

from kfserving import KFServingClient
kf = KFServingClient()
kf.get()

1. this code return error:

HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"inferenceservices.serving.kubeflow.org is forbidden: User \"system:serviceaccount:test:default-editor\" cannot list resource \"inferenceservices\" in API group \"serving.kubeflow.org\" in the namespace \"test\"","reason":"Forbidden","details":{"group":"serving.kubeflow.org","kind":"inferenceservices"},"code":403}

but I can use it deploy my inferenceservice before I upgrade.

How to upgrade kfserving that is no error?

FYI, https://github.com/kubeflow/kfserving/blob/master/install/v0.5.1/kfserving_kubeflow.yaml was added recently and should be applied when installing with Kubeflow. I am wondering if you applied the kfserving.yaml file which has the kfserving ingress gateway configured to the Knative gateway instead of the Kubeflow gateway.

Please use kubeflow 1.3 which is integrated with KFS 0.5.1 now
