Configure kubelet feature gates

With minikube this is set in the profile, and configured via
--feature-gates flag. With lima we can configure this directly in
KubeletConfiguration. Currently the feature gates are hard coded in the
configuration for all cluster. We can configure based on the profile
later if needed.
