[kubelet test] Improve node status test debug info
I find the output format `%v` of glog couldn't output useful information of an `api.Node` object. The output of this line https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/kubelet_node_status_test.go#L492
is
```
kubelet_node_status_test.go:491: expected
&TypeMeta{Kind:,APIVersion:,}
, got
&TypeMeta{Kind:,APIVersion:,}
```
- It's difficult for me to tell the difference between expected and got.
- I prefer to use `diff.ObjectDiff(expectedNode, updatedNode)` to output the debug information as it will point out the starting character of the different objects.
I think this line https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/kubelet_node_status_test.go#L647 can use `diff.ObjectDiff()` as well.
