Parallels Cloud Server uses virtual networks model for network
configuration. It uses own tools for virtual network management.
So add network driver, which will be responsible for listing
virtual networks and performing different operations on them
(in consequent patched).
This patch only allows listing virtual network names, without
any parameters like DHCP server settings.
