ApplyTo adds the admission chain to the server configuration the method lazily initializes a generic plugin that is appended to the list of pluginInitializers. apiserver.Config will hold an instance of SharedInformerFactory to ensure we only have once instance. The field will be initialized in apisever.SecureServingOptions
