4 The KeystoneNotificationTopics parameter was introduced. This takes a list
5 which will configure extra notification topics, which end up as queues in
6 the message broker. This is useful for when keystone notifications need to
7 be integrated with third party software. Note that enabling telemetry will
8 by default make keystone emit notifications to the 'notifications' topic, but
9 this parameter can enable extra topics still.
