    VMware: enable a resize of instance with no root disk
    
    This addresses the issue when the user wishes to update the CPU
    or memory of the instance.
    
    No changes to disks will be done if there is no root disk.
    
    Examples of when there is no root disk:
    1. When an instance is booted from a cinder volume.
    2. When booting from an ISO and the root disk size is zero
    
    In these cases there will not be a disk created on the vmware
    shared datastore.
