kubeadm: Add a `v1alpha3` API
**What this PR does / why we need it**:

Hopefully we'll graduate this to `v1beta1` during the v1.12 cycle.

**Special notes for your reviewer**:
These commits should be reviewed:
- `Add a duplicated v1alpha3 API`: A pure directory copy of the `v1alpha2` folder, only changed the package name in the Go files
- `Register the v1alpha3 API in the scheme, and update the roundtrip API tests`, started registering the new API and using it internally
- `Automated bump from v1alpha2 references to v1alpha3`: Replaced all v1alpha2 references with v1alpha3
**Release note**:

Add healthz check to ensure logging is not blocked
When running the apiserver/controllers in pods, we encountered a docker bug that blocked stdout/stderr (https://github.com/moby/moby/issues/31373)
That in turn blocked flushing logs, which in turn eventually blocked any goroutine that logs anything (which is pretty much all the important goroutines)
This adds a healthz check that logging is not blocked so that healthz indicates something is wrong
```release-note
NONE
```
