kubeadm: Replace *clientset.Clientset with clientset.Interface

**What this PR does / why we need it**:

Needed for https://github.com/kubernetes/kubernetes/pull/48899
We should always use `clientset.Interface` instead of `*clientset.Clientset`, for better testability and all the other benefits of using an interface.

**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #

**Special notes for your reviewer**:
Should be straightforward to merge

**Release note**:

```release-note
NONE
```
