Revert "Remove old node role label that is not used by kubeadm"
Revert the commit that removed printing of node roles from kubectl.

Kubelet manage hosts file for HostNetwork Pods instead of Docker
**What this PR does / why we need it**: Currently, Docker manages the hosts file for containers inside Pods using hostNetwork. It creates discrepancy between how we treat hostNetwork and non-hostNetwork Pods. Kubelet should manage the file regardless of the network setup.
**Which issue this PR fixes**: fixes#48397 more context in https://github.com/kubernetes/kubernetes/issues/43632#issuecomment-304376441
**Special notes for your reviewer**: Because the new logic relies on reading the node filesystem, I'm not sure how to write a proper unit test. I was thinking about using a node e2e test to cover the case, but suggestions are greatly welcomed.
**Release note**:
```release-note
Kubelet now manages `/etc/hosts` file for both hostNetwork Pods and non-hostNetwork Pods.

Validate token length of TokenReview
**What this PR does / why we need it**:
I find API Resource TokenReview has no validation yet. Without validation, client may post unexpected data to API Server. I think we need to validate it before processing it.
