Skip NoNewPrivileges test when SELinux is enabled
**What this PR does / why we need it**:
A bug in the SELinux policy prevented NoNewPrivileges from working on Docker with SELinux support enabled.
The problem has been fixed upstream (see projectatomic/container-selinux#45)
But hasn't been backported yet (a fix might come in RHEL 7.5)
For now, let's skip the NoNewPrivileges test when SELinux support is enabled in Docker.
Tested:
- Before this commit, the test fails:
```

kubelet: remove the rktshim directory
This package contains only placeholders without actual implementation.
Since it is not currently under active development, remove it to avoid
unnecessary change needed whenever the interface is changed.

It is not clear whether JobScaler could use generic scaler or not.

Removal of KubeletConfigFile feature gate: Step 1
This feature gate was redundant with the `--config` flag, which already
enables/disables loading Kubelet config from a file.
Since the gate guarded an alpha feature, removing it is not a violation
of our API guidelines.
Some stuff in `kubernetes/test-infra` currently sets the gate,
so removing will be a 3 step process:
1. This PR, which makes the gate a no-op.
2. Stop setting the gate in `kubernetes/test-infra`.
3. Completely remove the gate (this PR will get the release note).

Promote Statefulset controller and its e2e tests to use apps/v1
**What this PR does / why we need it**:
Promotes the statefulset controller to use to use the latest apps group [apps/v1](https://github.com/kubernetes/kubernetes/pull/53679)

Fixes # https://github.com/kubernetes/kubernetes/issues/55714
**Special notes for your reviewer**:
* Listerexpansion for v1 `k8s.io/client-go/listers/apps/v1` (was recently done for v1beta2)
* `v1beta2` && `v1` had `ObservedGeneration` as `int64` where as `v1beta1` and rest of the code (including conversion) is expecting `ObservedGeneration` to be `*int64`
```
type StatefulSetStatus struct {
// observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the
// StatefulSet's generation, which is updated on mutation by the API Server.
// +optional
ObservedGeneration int64 `json:"observedGeneration,omitempty" protobuf:"varint,1,opt,name=observedGeneration"`
```
* for kubectl's `rollback` and `history` commands a couple functions have been duplicated to allow us to use `v1` version instead of `v1beta1` for statefulsets, while the older functions are still used by other controllers.
We should be able to remove these duplicates once all the controllers are moved.
If this aligns with the plan then i could move other controllers too.

Created bootstrap logic for vSphere test
**What this PR does / why we need it**:
Add bootstrapping logic and Context for vSphere tests. This context can be utilized to hold information like node-vsphere mapping, which needs to be initialized only once per test suit run.
sync.Once takes care of executing bootstrapping only once for all the specs. 'waiting' channel takes care of making sure that parallel test spec executions wait for bootstrapping to finish before moving on.
**Which issue(s) this PR fixes**
Fixes https://github.com/vmware/kubernetes/issues/437, partly
**Special notes for your reviewer**:
Successfully ran make.
Tested by added additional log messages to bootstrap process (now removed). Made sure bootstrapping logic is getting invoked just once and bootstrapping is done by the time It-blocks are executed.

Rename package deviceplugin => devicemanager.
**What this PR does / why we need it**:
Fixes#58795
/kind cleanup
Rename package `deviceplugin` to `devicemanager` for consistency.
We already have components named Container manager and CPU manager. The device plugin package similarly contains an interface called `Manager`. The fact that the manager has plugins is somewhat incidental to the purpose of the package itself.
Note that this rename only affects internal API. The external gRPC interface still exports a package called deviceplugin.
