Live migration: wait for vif-plugged event on pre live migration

Just like with spawning new VM, we need to wait for neutron to properly
handle new vif device on pre migration step.

By default nova dispatches event to the instance's host while during
live migration we're waiting on destination host - the solution
is to check if instance is migrating and send event to destination
compute as well.
