    Revert "Revert resize: wait for events according to hybrid plug"
    
    This reverts commit 19f9b37721d9bc13bc1ed35a4f368b1d21b10a5b.
    
    Commit 19f9b37721d9bc13bc1ed35a4f368b1d21b10a5b introduced
    a regression and caused errors on Neutron CI jobs which run
    on a single node with iptables_hybrid firewall driver.
    This is because the nova change made the resize revert flow
    wait for neutron-vif-plugged events in the ComputeManager
    when the port's host binding changes for iptables_hybrid
    ports but for those types of ports, Neutron does not send
    the event if the host does not change - which is the case
    for a same-host resize being reverted.

Title:
  Revert resize tests are failing in jobs with iptables_hybrid fw driver

Status in neutron:
  Confirmed
Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Tests:

  tempest.api.compute.admin.test_migrations.MigrationsAdminTest.test_resize_server_revert_deleted_flavor
  tempest.api.compute.servers.test_server_actions.ServerActionsTestJSON.test_resize_server_revert
  tempest.api.compute.servers.test_server_actions.ServerActionsTestJSON.test_resize_server_revert_with_volume_attached

  are failing 100% times since last ~2 days.
  And it happens only in jobs with iptables_hybrid fw driver but I don't know if this is really some source of issue or maybe just red herring.
