While updates are managed through Nebraska, not every user wants to or can run their own service. Sometimes it would be more convenient if a local update command exists that also supports airgapped updates or helps a user to quickly jump between versions to reproduce an error. Add a flatcar-update tool (similar to flatcar-install) which users can run on the machine to force an update to a particular release or local update payload. On old machines this script can be fetched and executed, too, and should be CoreOS-compatible. Since update-engine does no version check, it's also possible to downgrade with the tool. The tool can disable updates after it ran, making it easy to do manual updates when no own Nebraska server exists.
