IPv4 subnet is required when creating a virtual network

[pertoft]

I am trying to create a virtual network with layer 2 service only (no ipv4 or ipv6 subnet enabled), but its not possible because ipv4 support is hard coded:

From blueprint.py line 2059:
virt_net = { "label": name, "security_zone_id": sz_id, "vn_type": vn_type.value, "vn_id": vn_id, "bound_to": bound_to, "ipv4_enabled": True, "dhcp_service": "dhcpServiceEnabled", "ipv4_subnet": ipv4_subnet, "ipv4_gateway": ipv4_gateway, }
The line "ipv4_enabled": True,
This should be changed to be an option which can be disabled.
