[LTP] [PATCH v5 6/8] network/route: Rewrite route{4, 6}-change-dst into new shell API

Petr Vorel
2019-10-11T13:24:31Z

* Drop route command (use just ip command), support both IPv4 and IPv6
* Add route-lib.sh (will be used in other route-change-*)
* Use unused network range to avoid clash with real network
* Add verification with ping (previous version sent UDP datagram with
ns-udpsender, but didn't verify receiving it on rhost and didn't setup
rhost ip at all)
