Remove RoutingDomain from ssh since it's now not needed. It can be replaced

with "route exec" or "nc -V" as a proxycommand.  "route exec" also ensures
that trafic such as DNS lookups stays withing the specified routingdomain.

For example (from reyk):
# route -T 2 exec /usr/sbin/sshd
or inherited from the parent process
$ route -T 2 exec sh
$ ssh 10.1.2.3
