process kubeadm joinToken,discoveryTokenCaCertHash,certificateKey

type Token struct {

	DiscoveryTokenCaCertHash []string `json:"discoveryTokenCaCertHash,omitempty"`
	CertificateKey           string   `json:"certificateKey,omitempty"`
}

1. use code generator 'CertificateKey' out struct 'CertificateKey'
