Revert "Merge pull request #51008 from kubernetes/revert-50789-fix-scheme"

I'm spinning up a cluster right now to test this fix, but I'm pretty sure this was the problem.
There doesn't seem to be a way to confirm from logs, because AFAICT the logs from the hollow kubelet containers are not collected as part of the kubemark test.

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

This reverts commit f4afdecef8, reversing
changes made to e633a1604f.

This also fixes a bug where Kubemark was still using the core api scheme
to manipulate the Kubelet's types, which was the cause of the initial
revert.

**Which issue this PR fixes**: fixes #51007

**Release note**:

```release-note
NONE
```
