Robert Kukura a9e3074aa9 ML2: ODL driver sets port status
The OpenDaylight mechanism driver does not depend on an L2 agent to
plug the port. Now that nova waits for notification that the port
status is ACTIVE, the ML2 driver API is extended so that the mechanism
driver that binds a port can optionally set the port status, and the
OpenDaylight mechanism driver uses this to set the port status to
ACTIVE.
