Change container-linux
module preference to Flatcar Linux
* No change to Fedora CoreOS modules * For Container Linx AWS and Azure, change the `os_image` default from coreos-stable to flatcar-stable * For Container Linux GCP and DigitalOcean, change `os_image` to be required since users should upload a Flatcar Linux image and set the variable * For Container Linux bare-metal, recommend users change the `os_channel` to Flatcar Linux. No actual module change.
