Kubelet flags are not necessarily appropriate for the KubeletConfiguration object. For example, this PR also removes HostnameOverride and NodeIP from KubeletConfiguration. This is a preleminary step to enabling Nodes to share configurations, as part of the dynamic Kubelet configuration feature (#29459). Fields that must be unique for each node inhibit sharing, because their values, by definition, cannot be shared.
