This patch introduces and implements Olso-Versioned Objects for
network extension External Networks.
There were joined performed to order the fetching of external
networks by standard attribute which seems useless because,
in networks/services/auto_allocated/db.py while fetching
external networks it logs error when multiple networks are
returned. Expected default external network there is one, so
ordering does not make much sense.
