    Skip templating disabled networks

    Ignore disabled networks when rendering templates.

    Add's the ctlplane network to maps to ensure we don't
    end up with no keys/values in map_replace functions.

    Also some Jinja cleanup:
     - Reduce the number of times we iterate over networks
       where we can.
     - Add's indentation to make the code easier to read.
