text: Title: Add non-serialized metrics tests for Windows
  Body: #### What happened:
  
  - Lets put a metrics CI job in place that isnt `Serial`.
  - Investigate our test coverage of metrics-server
  - See why our CI jobs dont test metrics-server
  - Confirm that we are doing enough in `kubelet_stats`
  
  #### What you expected to happen:
  
  https://github.com/kubernetes/kubernetes/blob/master/test/e2e/windows/kubelet_stats.go is a good test, lets make it part of all our containerd jobs by removing the Serial tags
