Code Issues Proposed changes

Update git submodules 

* Update oslo.utils from branch 'master'
  - Merge "eventletutils: Optimise EventletEvent.clear()"
  - eventletutils: Optimise EventletEvent.clear()
    
    When EventletEvent.clear() is called twice in succession without an
    intervening set(), there's no need to replace the underlying
    eventlet.event.Event object, since it has never been sent. Doing so
    would have woken other greenthreads waiting on the event to no
    particular end.
    
    When clear() is called after the event has been set(), we already did
    not do anything special with the existing eventlet.event.Event as we
    cannot call send() on it twice. We simply replace it with a new one; the
    code in wait() will handle the situation correctly, since it will wake
    up (due to the initial event having been sent) and begin waiting on the
    new eventlet.event.Event instead. This is consistent with the observed
    behaviour of threading.Event. A new unit test verifies this.
