Generate the self-signed CA to provision identities for etcd
Generate the self-signed CA to provision identities for etcd, and save them into etcd/ca.cert and etcd/ca.key files.
If both files already exist, kubeadm skips the generation step and existing files will be used.
Alpha Disclaimer: this command is currently alpha.
