Support override root name and generateName schema in crd

[liubog2008]

See https://github.com/kubernetes/enhancements/tree/master/keps/sig-api-machinery/2335-vanilla-crd-openapi-subset-structural-schemas#metadata

I want to change the pattern of the metadata.name.

When you say you would like to change the pattern, is that to say, you want to enforce some kind of regex on the value of the metadata.name field?

Have you considered using CEL?

type MyCustomResource struct {
  *metav1.TypeMeta `json:",inline"

  // +kubebuilder:validation:XValidation:rule="self.name.matches("<insert regex>"),message="CRD name must match..."
  *metav1.ObjectMeta `json:"metadata,omitempty"

  ...
}

That's what I need, thanks. I'll try it first
