Title:
  RequestSpec.ignore_hosts from resize is reused in subsequent evacuate

Status in OpenStack Compute (nova):
  Confirmed

Bug description:
  When doing a resize, if CONF.allow_resize_to_same_host is False, then
  we set RequestSpec.ignore_hosts and then save the RequestSpec.

  When we go to use the same RequestSpec on a subsequent
  rebuild/evacuate, ignore_hosts is still set from the previous resize.

  In RequestSpec.reset_forced_destinations() we reset force_hosts and
  force_nodes, it might make sense to also reset ignore_hosts.

  We may also want to change other things...for example in
  ConductorManager.rebuild_instance() we set request_spec.ignore_hosts
  to itself if it's set...that makes no sense if we're just going to
  reset it to nothing immediately afterwards.
