     *   3. Signer whose configured minimum is longer than the requested duration

     *   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.

     * 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.
