Add API validation

[cici37]

We have certain validation in place for built-in API such like

• validations or auditAnnotations must contain at least one item
• matchConstraints is required
• apiVersion is required is paramKind is present
• limitation on auditAnnotation
• ....

We could use x-kubernetes-validations for most of the checkings for CRDs. It will greatly help the future migration if we could match the API validation with built-in API.
