[PATCH 7/8] parallels: add routed pseudo network

[Dmitry Guryanov <dguryanov@xxxxxxxxxxxxx>]

Historically if traffic from the adapter is routed to LAN without
NAT, it isn't connected to any virtual networks, but has a 'type'
instead. Sinse libvirt has special virtual network type for such case,
let's add pseudo network 'routed' to fit libvirt's API well.
