    placement: Do not save 0-valued inventory

    Ironic nodes that are not available or operable have 0 values for vcpus,
    memory_mb, and local_gb in the returned dict from the Ironic virt driver's
    get_available_resource() call. Don't try to save these 0 values in the
    placement API inventory records, since the placement REST API will return an
    error. Instead, attempt to delete any inventory records for that Ironic node
    resource provider by PUT'ing an empty set of inventory records to the placement
    API.
