Update git submodules
* Update os-vif from branch 'master' to b837c1a74f37191692a820711e431a75516a4abf - add configurable per port bridges This patch add a new configuration option to use per port bridge when hybrid_plug is false. This can be used with OVN to reduce packet loss during a live migration. OVN can only install openflow rules when a port both has external_ids set and an ofport-id assigned. Since the ofport-id is only assigned when a netdev matching the port name exists connected to the dataplane, OVN cannot install the flows until libvirt create the tap on the destination host during a live migration. On loaded systems this can result in multiple seconds of packet loss. To address this we introduce per port bridges which are connencted to the integration brige by a patch port pair. Since the patch port will exist on the dataplane during pre live migration OVN can install the flows on the integration bridge before we begin the migration reducing or avoiding packet loss.
