• Needs to do an earlier return when it determines the Ingress is for a different controller.
• Should return a field.NotFound when the IngressClass doesn't exist.
• The validation of the link from IngressClass to IngressClassParams should be in a webhook on the IngressClass (this can be a separate PR)
