  - Updates to Common

    As part of updates to allotted resource, was reminded that the resource
    objects were not rooted (this was approved with temporary objects).
    Decided to make cross model updates to assure resource, service, nf,
    pnf, vnf, ... are all appropriately rooted as approved.   Some were
    rooted, some were not.    Also deleted all the temporary objects from
    common, which is also helpful from a glossary point of view.
