When trying to bring up a cluster via kubeadm with these feature gates enabled,
kube-proxy fails because it didn't know about them:
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker
featureGates: {"DynamicResourceAllocation":true,"ContextualLogging":true}
runtimeConfig: {"resource.k8s.io/v1alpha1":"true"}
=>
2023-01-20T07:07:54.474966617Z stderr F E0120 07:07:54.474846 1 run.go:74] "command failed" err="failed complete: unrecognized feature gate: ContextualLogging"
The effect of the logging feature gates is minor for kube-proxy, supporting
them is mostly useful for the sake of consistency and to support kubeadm.
