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.
