Refactor instance_usage_audit. Add audit tasklog.
The instance usage audit cronjob that generates periodic
compute.instance.exists notifications is not particularly scalable.
It is run on one server and takes longer as the number of instances grows.
This change moves the generation of those events to a periodic task in
the compute manager. It also adds an api extension that can be used
by administrators to check for errors generating these events.
