Add upgrades tests for kube-proxy daemonset migration path
**What this PR does / why we need it**:
From #23225, this is a part of setting up CIs to validate the kube-proxy migration path (static pods -> daemonset and reverse).
The other part of the works (adding real CIs that run these tests) will be in a separate PR against [kubernetes/test-infra](https://github.com/kubernetes/test-infra).
Though this is currently blocked by #50705.
