vz: assign static IPs and default gateways for network adapter

Browse Source 
We support only one IPv4 and one IPv6 default gateway.
If static IPs are not present in instance config,
then we switch on DHCP for this adapter.
PrlVmDevNet_SetAutoApply to makes necessary settings within guest OS
In linux case it creates network startup scripts
/etc/sysconfig/network-scripts/ifcfg-ethN and fills it with necessary
parameters.
