sysconfig: Raise ValueError when multiple default gateways are present.
Fixed setting Route.has_set_default_ipv6 or *_ipv4 to track whether a route already has a default gateway defined. The code was setting Route.has_set_default which wasn't checked when raising "duplicate gateway" ValueErrors. Added unit tests to exercise this expected raised ValueError. Also moved is_ipv6 = subnet.get('ipv6') logic out of a for loop because we don't need to recalculate the same value every route iteration. LP: #1687485
