Confirm behavior of offline flag
There's a discussion at the dev ops session at the Toyama LVK right now about how to upload offline results to gracedb. This issue is just to keep it on our radar to double check how the offline flag interacts with the alert system and then check if there's anything we need to adjust (related issue, #708 (closed)).
I told them that I believe everything runs as normal with the offline flag, other than the fact that offline flags won't trigger public alerts.
We should confirm that all of the annotations performed on offline events are actually desired, e.g. I cant remember if PE is run for events with the offline flag (I thought the answer was no but didn't see anything in the code to support that), but either way we should ask PE what they want. This is possibly taken care of by #707 (closed), but I'd like to confirm that.
