Cluster bootstrap start isn't idempotent

In case bootstrap failed and left some static manifests under the kubelet pod manifest path it will never clean it up.
See logs:

I'm unsure how the static pod manifests where left behind to begin with.
The issue is that the bootstrapControlPlane fail to start in case a static pod manifest with the same name already exist.
In that case ownedManifests won't be set and the manifests will not get deleted during Teardown.
This cycle will go on and on.
