On a second thought it might be not fair to require nova to wait for
some events from neutron on cleanup. Also in case of live migration vifs
on source node are deleted after vm is already migrated and ports are
active on destination node, so neutron will not send any network-vif-
unplugged events in this case. Shelve-unshelve seems a corner case and
I'd like to avoid hacks in vm cleanup logic.

The other idea for the fix (on neutron side now) would be to change port
status to smth like PENDING_BUILD right after db update. Nova will count
such ports as non-ACTIVE and will wait for network-vif-plugged events
for them. When agent requests info for the port, neutron server will
update status to BUILD. Later when agent reports device up, the port
will be put back into ACTIVE state and network-vif-plugged event will be
sent to nova.

Changing project back to neutron.
