[LTP] [RFC PATCH 1/2] net: Add tst_net_run helper

[Petr Vorel]

Signed-off-by: Petr Vorel <pvorel@suse.cz>

Changes v1->v2:
tst_net_driver removed and created generic command tst_net_run

TODO: For ROD it does not handle escape for >. E.g. it'd be nice to
handle this:
ROD foo \> bar.log
as passing the escape will not work for sh (non-safe local) and for
tst_rhost_run. Do we care?

Kind regards,
Petr
