I agree that I don't think it makes sense to have a whole new project just
for EventScheduler. Mistral seems like a pretty good fit. Convenience APIs
similar to the EventScheduler API for just saying "run this webhook on this
schedule" would be nice, too, but I wouldn't raise a fuss if they didn't
exist and I had to actually define a trivial workflow.
