[PATCH 08/10] *ConfigDevice: add VEth classes

[Ondrej Lichtner]

From: Ondrej Lichtner

This patch adds the classes NetConfigDeviceVEth and NmConfigDeviceVEth.
That represent configuration of veth type devices. Since NM doesn't
support veth devices, the NmConfigDeviceVEth class just to defines the
is_nm_managed method.
