Support for pruning of removed Kubernetes objects

Is there any thinking around whether Skaffold can or should support tracking of objects deployed to k8s, with a view of being able to delete those which no longer exist in the manifests?

### Expected behavior

If I deploy 2 Kubernetes objects from my manifest, then remove 1 object in my manifest and deploy again, the removed object should be deleted from the Kubernetes server.

### Actual behavior

The removed object is not deleted from Kubernetes.

### Information

- Contents of skaffold.yaml:

```yaml
apiVersion: skaffold/v4beta4
kind: Config
metadata:
name: skaffold-deploy
deploy:
kubectl:
manifests:
- nginx.yaml
```

- Contents of nginx.yaml:

```yaml
---
apiVersion: v1
kind: Service
metadata:
name: nginx-1
spec:
type: NodePort
ports:
- port: 80
targetPort: 80
nodePort: 30001
selector:
app: nginx
---
apiVersion: v1
kind: Service
metadata:
name: nginx-2
spec:
type: NodePort
ports:
- port: 80
targetPort: 80
nodePort: 30001
selector:
app: nginx
```

### Steps to reproduce the behavior

1. `skaffold deploy`
2. `yq eval-all 'select(.metadata.name == "nginx-1")' nginx.yaml > nginx-pruned.yaml && mv nginx-pruned.yaml nginx.yaml`
3. `skaffold deploy`
