audit_logs-server_stats

@chinguunhr , if you're interested in what GRR users did on specific GRR clients, then you should look in 2 places:

- Flows in "Managed launched flows" of every individual client. Flows can't be deleted and GRR users can only interact with any machine by running flows. By looking at flows you'll see everything that was collected/downloaded from the machine.
- If you're interested in a finer-grained audit log (who approved what, etc), we have a few audit reports available in "Server Stats" in the AdminUI.
