Kevin Benton 1b987be2b5 Use vif_type='tap' for LinuxBridge for consistency ... This adjusts the Linux Bridge mechanism driver to return the 'tap' VIF type to Nova so the Linux Bridge agent is responsible for plugging all ports into bridges. This completely eliminates all of the work Nova was doing with regard to bridges so we now have one consistent path how ports (both compute and dhcp/l3) are connected into Linux Bridge networks. Both Nova and the DHCP/L3 agents will now just create a device and leave wiring to bridges to be completely the responsibility of the L2 agent. In order to preserve backwards compatibiliy with Ocata agents that won't touch compute ports, we only report back vif_type='tap' if the agent has a report_state value showing that it wires compute ports. This will also solve a longstanding bug (bug #1105488) that is preventing Nova instances from using custom bridge mappings since the agent will be guaranteed to be responsible for the connection to the bridge.
