[Bug 1399249] [NEW] Neutron openvswitch-agent doesn't recover ports from binding_failed status
Public bug reported:
Ports created when neutron-openvswitch-agent is down are in status down
and "binding:vif_type=binding_failed" which is as it should be. When the
agent is rebooted it should be able to recreate the ports according to
the DB, but instead it logs a WARNING and creates the port with status
DOWN. only solution is to delete the port and create it again
