This is initial commit of the installer. What's done: - verifying node availability before starting any operations. - gathering information about disks on the machine. - allows setting: install disk, hostname, machine type, installer image, kubernetes version, dns domain, cluster-name. - dumps/merges talosconfig to a file after applying configuration.
