off topic:
- where can one find the minimum supported version of CAPBK in docs or YAML?
- does CABK error out if the user version is older than the minimum?

With this change CABPK will error out for Kubernetes < v1.13, while before things were failing in the cloud init script (which is much more complex to debug).

Let's move the checks above to a validation webhook?

I will open an issue to discuss this improvement.
The problem here is that this is a CABPK limitation, but the version could be defined on another resource (e.g. Machine deployments)
For the sake of this PR this is a little bit out of topic and this will also deviate from the original PR we are back porting.
Nevertheless we are already improving the status quo, so I hop this should not be a blocker

What this PR does / why we need it:
backport of #4227
This PR implements a stop-gap solution for kubeadm types removal explicitly designed for back-porting on the v1alpha3 branch.
The solution implemented is described in the #4170 (and more specifically this is alternative 2 for v1alpha3).
A proper conversion mechanism is going to be implemented in v1alpha4 only (also described in the proposal).
