fedora-cloud-launch-gce-cli

	Created google-fedora-metadata-keys following instructions here: https://wiki.ubuntu.com/GoogleComputeEngineSSHKeys
	I used 'fedora', 'cloudinit', and 'root' as usernames there, most likely just 'fedora' would be required/needed.

	Converted qcow2 image to raw using qemu-img convert command, followed instructions here to import into GCE appropriately: https://major.io/2019/08/07/fedora-30-on-google-compute-engine/

	Create instance (you probably don't need to specify all these options, this was copied from the web interface for convenience)
