Scenario request: Continue as new on workflow with lots of events

[cretz]

Describe the scenario you'd like

Run <workflow-count> workflows that generate <event-count> events (sequential activities with fake input/output payload, combine with some fake signals for example) and then continue as new. The workflow should do this event-build-and-continue-as-new <continue-as-new-iterations> times. May want to break up events with only so many in a single task instead of all in one.

The variables can be set based on good numbers that stress the environment.
