kubectl failed to delete uninitialized resources

[dixudx]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind bug
/sig cli

What happened:

This is not a dup of #49035.

kubectl cannot delete resources of Deployment/ReplicaSet/StatefulSet when enabling initializers. But works well for other kind of resources.

What you expected to happen:
Successfully delete them.

How to reproduce it (as minimally and precisely as possible):

1. Create a deployment with initializer:

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: web
  labels:
    run: web
  initializers:
    pending:
    - name: podimage.initializer.com
spec:
  replicas: 5
  selector:
    matchLabels:
      run: web
  template:
    metadata:
      labels:
        run: web
    spec:
      containers:
      - image: nginx:1.10
        name: web
        ports:
        - containerPort: 80
          protocol: TCP

Then create using

$ kubectl create -f above.yaml

Currently you cannot see it using kubectl get deploy before #50497 get merged (kubectl get deploy --include-unintialized).

But getting a single resource still works,

$ kubectl get deploy web
NAME      DESIRED   CURRENT   UP-TO-DATE   AVAILABLE   AGE
web       5         0         0            0           1m

2. Delete the deployment

$ kubectl delete -v 10 deploy web

The deployment web cannot be deleted and the requests keep performing GET https://172.17.8.101/apis/extensions/v1beta1/namespaces/default/deployments/web. And the response body stays unchanged.
