**Release note**:
```release-note
NONE
```
This change allows the RBAC PostStartHook logic to be reused with
different policy data when bootstrapping the cluster. Thus any
changes to the bootstrap logic are separated from the policy data.

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.

advanced audit: shutdown batching audit webhook gracefully
Follow-up of https://github.com/kubernetes/kubernetes/pull/50439
When the `stopCh` passed to the batching audit webhook is closed, it stops accepting new events and when `Shutdown` method is called afterwards, it blocks until the last request to the webhook has finished.

**Special notes for your reviewer**:
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.

[Federation] Kubefed doc fix
Fixes https://github.com/kubernetes/kubernetes/issues/50615
@kubernetes/sig-federation-bugs
@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.
**Release note**:

kubeadm: Implementing the controlplane phase
**What this PR does / why we need it:**
This contains implementation of controlplane phases in kubeadm, which is part of the wider effort of implementing phases in kubeadm, previously in alpha stage.
The original proposal for this activity can be found [here](https://github.com/kubernetes/kubeadm/pull/156/files) and related comments.
Kubeadm phase implementation checklist is defined [here](https://github.com/kubernetes/kubeadm/issues/267)
Common implementation guidelines and principles for all phases are defined [here](https://docs.google.com/document/d/1VQMyFIVMfRGQPP3oCUpfjiWtOr3pLxp4g7cP-hXQFXc/edit?usp=sharing)
This PR implements:
- [x] kubeadm phase controlplane: wip by @fabriziopandini
- [x] kubeadm phase controlplane all
- [x] kubeadm phase controlplane etcd
- [x] kubeadm phase controlplane apiserver
- [x] kubeadm phase controlplane scheduler
- [x] kubeadm phase controlplane controller-manager
**Which issue this PR fixes:**
https://github.com/kubernetes/kubeadm/issues/349
**Special notes for your reviewer:**
This PR implements the same approach of #49419, thus minimising rework/impacts on existing codebase.
LocalVolumeType tmpfs added
Added checks to ensure tha volume created during setup contains expected testFileContent
Refactored tests out to avoid code duplication
Two different tests are performed with tmpfs:
-serial write and read in two different pods
-write and read in two different pods mounted at the same time
Fixed local storage test failures by integrating https://github.com/kubernetes/kubernetes/pull/50177
