some final changes

a.) do not write systemd link files if we do not have a mac address.
    the check is updated to check for value rather than just presense
    (ie, 'mac_address': None)

b.) DataSourceNoCloudNet: search in the nocloud seed dir
    this is important because NoCloud if dsmode is Net will look only
    would pass by, expecting NoCloudNet to pick it up
    but NoCloudNet would not look in /var/lib/cloud/seed/nocloud
    and thus skip it.

c.) support the disabling of network configuration 
    via /var/lib/cloud/data/upgraded-network
    This is what the package upgrader is writing.
