	// List/watch requests for CertificateSigningRequests can filter on this field using a "spec.signerName=NAME" fieldSelector.
	//
	// Well-known Kubernetes signers are:
	//  1. "kubernetes.io/kube-apiserver-client": issues client certificates that can be used to authenticate to kube-apiserver.
	//   Requests for this signer are never auto-approved by kube-controller-manager, can be issued by the "csrsigning" controller in kube-controller-manager.
	//  2. "kubernetes.io/kube-apiserver-client-kubelet": issues client certificates that kubelets use to authenticate to kube-apiserver.
	//   Requests for this signer can be auto-approved by the "csrapproving" controller in kube-controller-manager, and can be issued by the "csrsigning" controller in kube-controller-manager.
	//  3. "kubernetes.io/kubelet-serving" issues serving certificates that kubelets use to serve TLS endpoints, which kube-apiserver can connect to securely.
	//   Requests for this signer are never auto-approved by kube-controller-manager, and can be issued by the "csrsigning" controller in kube-controller-manager.
	//
	// More details are available at https://k8s.io/docs/reference/access-authn-authz/certificate-signing-requests/#kubernetes-signers
	//
	// Custom signerNames can also be specified. The signer defines:
	//  1. Trust distribution: how trust (CA bundles) are distributed.
	//  2. Permitted subjects: and behavior when a disallowed subject is requested.
	//  3. Required, permitted, or forbidden x509 extensions in the request (including whether subjectAltNames are allowed, which types, restrictions on allowed values) and behavior when a disallowed extension is requested.
	//  4. Required, permitted, or forbidden key usages / extended key usages.
	//  5. Expiration/certificate lifetime: whether it is fixed by the signer, configurable by the admin.
	//  6. Whether or not requests for CA certificates are allowed.
	SignerName string

	// usages specifies a set of usage contexts the key will be
	// valid for.
	// See: https://tools.ietf.org/html/rfc5280#section-4.2.1.3
