Nodecontroller doesn't flip readiness on pods if kubeletVersion < 1.2.0

Older versions of the kubelet didn't know how to reconcile pod.Status, so the nodecontroller would mark pods NotReady on netsplit, and if the partition recovered in < 5m, the pods would never get marked Ready resulting in NotReady endpoints indefinitely (till kubelet restart/pod recreate etc).

Display one or many resources.

Possible resource types include (case insensitive): pods (aka 'po'), services (aka 'svc'), deployments (aka 'deploy'),
replicasets (aka 'rs'), replicationcontrollers (aka 'rc'), nodes (aka 'no'), events (aka 'ev'), limitranges (aka 'limits'),
persistentvolumes (aka 'pv'), persistentvolumeclaims (aka 'pvc'), resourcequotas (aka 'quota'), namespaces (aka 'ns'),
serviceaccounts (aka 'sa'), ingresses (aka 'ing'), horizontalpodautoscalers (aka 'hpa'), daemonsets (aka 'ds'), configmaps (aka 'cm'),
componentstatuses (aka 'cs), endpoints (aka 'ep'), petsets (alpha feature, may be unstable) and secrets.

This command will hide resources that have completed. For instance, pods that are in the Succeeded or Failed phases.
You can see the full results for any resource by providing the '--show-all' flag.

By specifying the output as 'template' and providing a Go template as the value
of the --template flag, you can filter the attributes of the fetched resource(s).

Add note: kubelet manages only k8s containers.

Kubelet wrote log when accesing container which was not created in k8s, what could confuse users. That's why we added note about it in documentation and lowered log level of the message to 5.

Here is example of the message: 
```
