Title:
  neutron unit tests break with oslo.utils 3.39.1 and above

Status in neutron:
  Invalid
Status in oslo.utils:
  Fix Released

Bug description:
  The new oslo.service version bump [1] is failing on the Neutron
  "test_periodic_worker_lifecycle" unit test [2].  This occurs when
  oslo.utils 3.39.1 or higher is installed; technically 3.38.0 is what
  is set forth in upper-constraints.txt [3] but you can see oslo.utils
  3.40.1 being installed in the failing tests [4].

  The change in oslo.config that is precipitating this failure is "Fix
  race condition in eventletutils Event" [5].  This is now included as a
  result of the bump for oslo.utils in upper-constraints.txt [6] that
  occurred yesterday (Jan 21 2019).

  As a temporary measure, will alter Neutron requirements.txt to cap the
  oslo.utils version at 3.39.0 or less so this issue can be fixed.
