Very temporary patch for the image type problem at Utah Cloudlab:
If the metadata does not include an architecture then we fall back to old method of allowing imported image to run on all local node types. This works pretty all the time on all clusters, but not on Cloudlab Utah which has ARM and X96 nodes. So for now, I have pushed out a change to all our clusters that forces an architecture into the metadata, based on the fact that if the local testbed does not have any m400 nodes, then the image is 99.9 percent certain to be x86_64. I will think about a proper solution on the way to Italy.
