The reason for the issue is that the apiserver uses the Scheme in the
global variable pkg/api/legacyscheme/scheme.go, and registers the
DeleteOptions corresponding to each APIGroup in the Scheme. But
DeleteOptions in meta.k8s.io/v1 is not registered, resulting
in a notRegisteredErr.
Use metainternalversionscheme.Codecs as Serializer
