What this PR does / why we need it:

AS-IS: When using the kubernetes/kubeadm role in a cluster using kube-proxy, the kube-proxy DaemonSet Pods are restarted everytime.

TO-BE: The kube-proxy DaemonSet Pods are restarted only if there are changes in the kube-proxy ConfigMap within the kube-system namespace. This can be achieved by simply comparing the resourceVersion of the ConfigMap before and after the tasks to detect any changes. This can reduce unnecessary restarts.

Which issue(s) this PR fixes:

Fixes #11400

Hi @Looka149. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
