Add a split horizon resolv.conf

- in default namespace, point to 194.1.163.3 and .4
- in dataplane namespace, point to lab.ipng.ch (192.168.1X.4 and 2001:678:d78:2X1::ffff)
- renumber ipv4 transit nets, so that .4/31 is labX.lab.ipng.ch <-> e0.vppX-0
- refactor common args (like nameserver search paths, node count, etc)

Regenerate the whole thing.
