Michael Still b7cb3b7523 Only setup iptables for metadata if using nova-net
As discussed in the bug report, we setup iptables rules for the metadata
service even if we're using neutron (which routes to metadata in a
different way). This is because of the split-brain behaviour of the
network driver interface versus the network API interface.

Instead, only setup iptables if we are _not_ using neutron.
