This change modifies _get_neutron_events_for_live_migration
to filter the event to just the subset that will be sent
at plug-time.
Currently neuton has a bug where by the dhcp agent
send a network-vif-plugged event during live migration after
we update the port profile with "migrating-to:"
this cause a network-vif-plugged event to be sent for
configuration where vif_plugging in nova/os-vif is a noop.
when that is corrected the current logic in nova cause the migration
to time out as its waiting for an event that will never arrive.
This change filters the set of events we wait for to just the plug
time events.
