reopen pr https://github.com/kubernetes/kubernetes/pull/40984, implement part of https://github.com/kubernetes/community/pull/287
for now unit test all pass, the output looks like:

apiVersion: extensions/v1beta1

metadata:
  creationTimestamp: null
  name: nginx-deployment

  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: nginx
    spec:
      containers:
      - image: nginx:1.12.10
        name: nginx
        ports:
        - containerPort: 80
        resources: {}
status: {}
```

```release-note
Support new kubectl apply view-last-applied command for viewing the last configuration file applied
