kube-proxymetricsBindAddress potentially lost on upgrade

[mnaser]

I am noticing that potentially metricsBindAddres is getting lost on cluster upgrades, so potentially we can add into this.

[jessica-hofmeister]

on creating a new cluster, we checked the configmap for kube-proxy in the kube-system namespace.
The metrics bind address is showing as empty upon create.
metricsBindAddress: ""

Per @mnaser's request, here is the contents of the kubeadm.yaml file found in /run/kubeadm

sudo cat kubeadm.yaml
