    Fix custom network.name_lower in krb-service-principals

    The lowercase network names was hardcoded to 'external',
    'internal_api' and 'storage_mgmt'. Use jinja to get the
    network.name_lower value from network_data.yaml instead
    so that users can customize the lowercase network name.
