OpenStack Networking (Neutron)

During some ml2 ovs agent port processing performance test, we noticed that some ports are missing tag before it really done processing. While ovs treats those ports without tag as trunk port, so some packets will be flooded to it. In large scale cloud, if too many port added to the bridge, the ovs-vswitchd will consume a huge amount of CPU cores if ports are not bound in a short time. So, in the port_bound function of ovs-agent, we set the port tag to it after a local_vlan id is allocated. Because after that, setup security groups (setup_port_filters) and bind devices in DB (update_device_list) are really time-consuming. And also fix a potential bug, port is processed as created first, but no tag in ovsdb, so openflow security group will not be processed successfully [1]. It must be done in a update event during next loop, after port bound and ovsdb set the required value. This patch can also fix some upstream test failures of waiting too long time to ping some cases.
