steigr 5421068656 Print output of ip route command as string. (#439)
`Cmd.CombinedOutput()` returns `[]byte` for the command output which, at least for `ip` commands should be a printable string. The output is now printed as string.

Furthermore the constant `KUBE_DUMMY_IF` is used for the interface name to reduce multiple definitions of the interface name.
