Create flavors describing the compute resources the cloud has
available.
If the list of flavors is only meant to encompass hardware that the cloud
has available, a JSON file describing the nodes can be specified, see
register-nodes for the format.
If a custom list of flavors is to be created, they can be specified as a
list of JSON objects. Each list item is a JSON object describing one
flavor, which has a "name" for the flavor, "memory" in MB, "cpu" in
threads, "disk" in GB and "arch" as one of i386/amd64/etc.
