Handle deleted DaemonSet properly
**What this PR does / why we need it**:
After kubectl reapers are removed (#63979) and foreground deletion are used, DaemonSet controller may race with garbage collector when it tries to update DaemonSet status of the DaemonSet being deleted.
Here's what happened:
1. Someone/something performs a foreground deletion on a DaemonSet
1. DaemonSet finalizer and DeletionTimestamp are both set
1. DaemonSet history objects (ControllerRevisions) and pods are being deleted by garbage collector; meanwhile, DaemonSet controller tries to update DaemonSet status.
* Updating DaemonSet status requires constructing DaemonSet history objects, to figure out current revision and which pods do/don't belong to current revision
1. When updating DaemonSet status, DaemonSet controller tries to create a DaemonSet history object that matches current DaemonSet spec
1. Garbage collector then tries to delete that DaemonSet history object. And repeat.
Because we can't make DaemonSet pods be deleted before DaemonSet history objects (DaemonSet history objects don't own DaemonSet pods!), we cannot reliably calculate DaemonSet status without history objects anyways. Therefore, we don't update DaemonSet status for DaemonSet being deleted.
Note that the reason why the kubectl delete hack works is because it forces DaemonSet pods to be removed before history objects.

remove extra "../" when copying from pod to local
**Release note**:
```release-note
NONE
```
Copying via `kubectl cp` from a pod to local will no longer panic if any received tar headers contain an extra "../". This can happen when specifying a remote location beyond "/" - for example:
```
# I am attempting to go backwards beyond "/"
$ kubectl cp mypod:/one/two/../../../etc/hosts ./
```
The above command results in a tar header containing an extra "../" in its name (../etc/hosts), causing a panic [here](https://github.com/kubernetes/kubernetes/blob/master/pkg/kubectl/cmd/cp.go#L388).

switch rbac to external
The overall trajectory of the project is towards external types. Having all helpers agree on the version they operate on makes life much easier.

This pull switches all the core helpers over to use the external types.

Tolarate negative values when calculating job scale progress
**What this PR does / why we need it**:
It might happen that the job controller will complete a job, but the status will still contain information about active pods which during scale down operation will be giving false (non 0) value in [this calculation](1b950d1e8e/pkg/kubectl/cmd/scalejob/scalejob.go (L147)).
