move KubeletConfiguration out of componentconfig API group
I'm splitting #44252 into more manageable steps. This step moves the types and updates references.
To reviewers: the most important changes are the removals from pkg/apis/componentconfig and additions to pkg/kubelet/apis/kubeletconfig. Almost everything else is an import or name update.
I have one unanswered question: Should I create a whole new api scheme for Kubelet APIs rather than register e.g. a kubeletconfig group with the default runtime.Scheme instance? This feels like the right thing, as the Kubelet should be exposing its own API, but there's a big fat warning not to do this in `pkg/api/register.go`. Can anyone answer this?

Correct case for starting character of option string
**What this PR does / why we need it**:
Kubectl-conventions.md states:
"Flag descriptions should start with an uppercase letter and not have a period at the end of a sentence"
There are numerous cases where this is violated in `kubectl/cmd`. This PR is the result of an audit of all source files under `kublet/cmd` and corrects the case of the initial Flag description character.

Although we do locking/unlocking while using protected data in ClusterController, there are chances that `clusterClient` can be deleted as it is a pointer. Also its better to lock/unlock once for the function `UpdateClusterStatus` instead of multiple locks/unlocks.

Remove the status of the terminated containers in the summary endpoint
Ref: https://github.com/kubernetes/kubernetes/issues/47853
- When building summary, a container is considered to be terminated if it has an older creation time and no CPU instantaneous or memory RSS usage.
- We remove the terminated containers in the summary by grouping the containers with the same name in the same pod, sorting them in each group by creation time, and skipping the oldest ones with no usage in each group. Let me know if there's simpler way.

@madhusudancs, would it be of any reason to have separate code for kubefed for the version and options subcommands (rather then using ```kubectl.NewCmdVersion()``` and ```kubectl.NewCmdOptions```). I dont see the need, but I might be missing something.

Fix kubernetes-worker charm hook failure when applying labels
**What this PR does / why we need it**:
This fixes a failure that can occur in the kubernetes-worker charm when trying to apply node labels.
The failure is rare, and can occur in two situations that I've seen:
1. kube-apiserver is not up yet
2. kubelet has not registered itself as a node yet
Rather than give up right away, let's give the services a minute to come up.
