fix(vm,lxc): accept IPv6 in initialization.dns.servers attribute

[LEI]

While trying to setup both IPv4 and IPv6 addresses in a VM, a validation error prevents adding IPv6 DNS in Cloud-Init initialization:

Error: expected initialization.0.dns.0.servers.1 to contain a valid IPv4 address, got: x:x:x:x:x:x

Proxmox seems to accept both there, I have yet to get IPv6 connectivity working though.

make example fails due to an SSH connection error with my setup, but I guess only IPv4 is tested anyway.
