    Update scheduler instance info at confirm resize

    When a resize is confirmed the instance does not belong to the source
    compute any more. In the past the scheduler instance info is only
    updated by the _sync_scheduler_instance_info periodic. This caused that
    server boots with anti-affinity did not consider the source host.
    But now at the end of the confirm_resize call the compute also updates
    the scheduler about the move.

    Conflicts:
      nova/compute/manager.py due to
      I933687891abef4878de09481937d576ce5899511 is a stable only patch
      nova/tests/unit/compute/test_compute_mgr.py due to
      35ce77835bb271bad3c18eaf22146edac3a42ea0 is missing from stable/rocky
