Zane Bitter cc8b51e1e1 Fix race condition in eventletutils Event

The threading-compatible eventlet Event class has a race condition on
the wait method. If greenthread A is blocked on the wait, but another
greenthread B calls clear() and then set(), B calls self._event.send(),
but A is waiting on a different eventlet Event which is no longer used
by the oslo.service Event...

To resolve this, when clearing an Event trigger the underlying eventlet
Event immediately, then have the wait() method resume waiting on the new
eventlet Event.
