Implement --prune-whitelist(-w) flag to overwrite default whitelist for --prune

From #34274.

Updates:

As suggested, the new commits implement a default whitelist for `kubectl apply --prune`, which could be overwritten by using `--prune-whitelist`or `-w` flag. The default whitelist and example as below.

Also supports `--dry-run` for `--prune` to fix #35222.

whitelist:

```
type pruneResource struct {
    group      string
    version    string
    kind       string
    namespaced bool
}

*pruneResources = []pruneResource{
    {"", "v1", "ConfigMap", true},
    {"", "v1", "Endpoints", true},
    {"", "v1", "Namespace", false},
    {"", "v1", "PersistentVolumeClaim", true},
    {"", "v1", "PersistentVolume", false},
    {"", "v1", "Pod", true},
    {"", "v1", "ReplicationController", true},
    {"", "v1", "Secret", true},
    {"", "v1", "Service", true},
    {"batch", "v1", "Job", true},
    {"extensions", "v1beta1", "DaemonSet", true},
    {"extensions", "v1beta1", "Deployment", true},
    {"extensions", "v1beta1", "HorizontalPodAutoscaler", true},
    {"extensions", "v1beta1", "Ingress", true},
    {"extensions", "v1beta1", "ReplicaSet", true},
    {"apps", "v1beta1", "StatefulSet", true},
}
```

example:

```
$ kubectl apply -f /path/to/file --prune -l test=true \
      -w core/v1/Pod \
      -w core/v1/Service \
      -w extensions/v1beta1/Deployment 
```
