kube-proxy: support the logging feature gates

Browse Source 
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.
