refactor to get better data into .treeinfo
    
    for https://fedorahosted.org/rel-eng/ticket/6008 refacter how we deal
    with the data that feeds into .treeinfo
    Deprecate --name for --family
    Deprecate --flavor for --variant
    rather than using --name as the iso base name use the value of
    family if there is a variant add it with a - as the seperator
