(3:18:02 PM) slaweq: mriedem: it's not a race
(3:18:30 PM) slaweq: mriedem: I saw it already before, it's some issue with neutron that it process request very slow, see: http://logs.openstack.org/70/605270/1/gate/tempest-full-py3/f18bf28/controller/logs/screen-q-svc.txt.gz?level=INFO#_Sep_27_01_11_47_552844
(3:19:12 PM) slaweq: so first request is processed very long, and tempest client has http timeout, so client retries same request but then network is already removed
(3:19:14 PM) mriedem: time: 66.6156189
(3:19:19 PM) mriedem: wow
(3:19:19 PM) slaweq: exacly :/

Title:
  NetworkNotFound failures on network test teardown

Status in neutron:
  New
Status in tempest:
  Invalid

Bug description:
  I've seen this in a few different tests and branches, network tests
  are tearing down and hitting NetworkNotFound presumably because the
  test already deleted the network and we're racing on teardown:

  http://logs.openstack.org/70/605270/1/gate/tempest-full-
  py3/f18bf28/testr_results.html.gz

  Traceback (most recent call last):
    File "/opt/stack/tempest/tempest/lib/services/network/networks_client.py", line 52, in delete_network
      return self.delete_resource(uri)
    File "/opt/stack/tempest/tempest/lib/services/network/base.py", line 41, in delete_resource
      resp, body = self.delete(req_uri)
    File "/opt/stack/tempest/tempest/lib/common/rest_client.py", line 310, in delete
      return self.request('DELETE', url, extra_headers, headers, body)
    File "/opt/stack/tempest/tempest/lib/common/rest_client.py", line 675, in request
      self._error_checker(resp, resp_body)
    File "/opt/stack/tempest/tempest/lib/common/rest_client.py", line 781, in _error_checker
      raise exceptions.NotFound(resp_body, resp=resp)
  tempest.lib.exceptions.NotFound: Object not found
  Details: {'detail': '', 'type': 'NetworkNotFound', 'message': 'Network 0574d093-73f1-4a7c-b0d8-49c9f43d44fa could not be found.'}

  We should just handle the 404 and ignore it since we're trying to
  delete the network anyway.
