Add "consoles" to setup different "equipment"

[KOLANICH]

A "console" should understand syntax of CLI commands like ip route add ... and ip link eth0 set ... and ip rule show and do actions like the ones done by the command, but on a virtual device. There should be multiple modes of the console, i.e. one for tools available on linuxes via CLI, i.e. ip, ifconfig, iptables and one for cisco-like syntax.
