Before this patch, when migrating from ML2/OVS to ML2/OVN, we removed the VIF details that are not used by OVN. However, this changes how the VIFs are plugged if the hybrid iptables firewall was used. In order to not break the migration, we want to keep whatever plugging was used in ML2/OVS. For this reason, this patch is leaving the VIF details untouched. The consequence is that, after migration, whatever workloads used the hybrid plugging will remain like that. Newly created VIFs will be plugged to the OVS bridge directly. As a result, the migration to OVN won't require moving to the OVS firewall first while in ML2/OVS. This patch is also removing the constraint that prevented the migration if the hybrid firewall was used.
