Parses notification data to identify if the event is related to delete

to KeystoneEventConsumer logic for further processing. Barbican service
is not interested in other events so in that case it just returns None
as acknowledgment.
Messaging server considers message is acknowledged when either return
value is `oslo_messaging.NotificationResult.HANDLED` or None.
In case of successful processing of notification, the returned value is
`oslo_messaging.NotificationResult.HANDLED`
In case of notification processing error, the value returned
is oslo_messaging.NotificationResult.REQUEUE when transport
supports this feature otherwise
`oslo_messaging.NotificationResult.HANDLED` is returned.
