How to use

Testing done

The version was overwritten in case the CoreOS node was on a newer
version than what Flatcar Stable offers. Now this can't be the case
anymore.
Drop the version overwriting.
The check for the migration of the baked-in userdata would also return
an error code if it was run as last step.
In case it gets moved, rather use an if block which captures the return
code.

The update and rollback docs had a lot of manual steps, some like the
restarting of update-engine were not really necessary.

Make use of the migration script that we maintain instead of outlining
manual steps to update from CoreOS. Also make use of the new
"flatcar-update" tool which allows to do an easy rollback to any older
version.
