Merge pull request #68077 from DirectXMan12/deployments/metrics-server-v0.3.0

Automatic merge from submit-queue (batch tested with PRs 68044, 68077). If you want to cherry-pick this change to another branch, please follow the instructions here: https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md. Update metrics-server to v0.3.0 v0.3.0 is the latest version of metrics-server, and brings a number of internal stability improvements as well as some bugfixes and features. NB: this currently disables Kubelet auth entirely, since this setup needs to work on GKE for the tests, and GKE doesn't support delegated Kubelet auth yet. When that's rectified, we can switch this over to use secure options. ```release-note Update metrics-server to v0.3.0. ```
