Title:
  Trunk status is down after a live-migration

Status in neutron:
  Fix Released

Bug description:
  After live-migrating a trunk VM the network trunk status remains in a
  DOWN state even if the subports and parent port status is ACTIVE and
  there is connectivity between subports and to the trunk port.

  stepts to reproduce:
  1. Create trunk with some subport,
  2. Spawn vm with plugged to the trunk's parent port,
  3. Check status of trunk's parent port, subport's port and trunk itself- all ACTIVE
  4. Live-migrate vm
  5. Check status of trunk's parent port and subport's port and trunk itself - subport and parent port status is UP but trunk itself has DOWN status.
