Description

Mirror Cadence feature request(with proposal): https://github.com/uber/cadence/issues/3914

cc @yux0 @yycptt @meiliang86 LMK if you have any plan to implement this feature :D
This becomes problematic because people want to use ChildWorkflow naturally. today, a workflow with childWorkflow can be not resettable which will be hard to recover from outage.
