I noticed this while investigating public nova bug 1673375, but it
looks like that bug is caused by a ValueError coming from the
oslo.messaging notification code, related to a circular reference in
the json blob:

The security issue here is that the notification payload that's logged
has all kinds of auth secrets in it, like tokens and passwords.
From logstash it looks like this is only hitting master (pike) right
now.
