parallels: parse information about network interfaces

Browse Source 
Parse network interfaces info from prlctl output.

Parallels Cloud Server uses virtual networks model for
network configuration: You can add network adapter to
VM and connect it to some predefined virtual network.

Fill type, mac, network name and linkstate fields of
virDomainNetDef structure.
