After today's SIG meeting, it was discussed how to proceed with these
types of test-cmd tests. They will live in kubeamd/test/cmd and will
provide a flag that will allow you to skip them (--kubeadm-cmd-skip) and
by default will fail if kubeadm binary is not present
Adds kubeadm subcommands to create, list, and delete bootstrap tokens.
Tokens can be created with a TTL duration, or 0 for tokens that will not
expire. The create command can also be used to specify your own token
(for use when bootstrapping masters and nodes in parallel), or update an
existing token's secret or ttl.
Marked "ex" for experimental for now as the boostrap controllers are not
yet hooked up in core.
