[RFC PATCH ve-rs 01/16] ve-config: sdn: add ovn zone type

["Rémi PAETA" <remi.paeta@comaite.com>]

pve-network gains an "ovn" zone type. An unknown zone type makes the
parsing of the whole SDN running configuration fail, so
proxmox-firewall would stop generating any rule on nodes with OVN
zones, for all guests.

The zone type does not need any specific handling: OVN zones only
carry vnets and subnets like the other zone types.
