Notify when flow does not satisfies the expected result. #2

Right now, when executing the flow, we specify the desired results in the third parameter, for example

const response = await FlowManager.run(
      flowDefinition,
      parameters,
      ['myResponse'],
      resolvers,
);

But, when for whatever reason (for example a cyclic flow or and unintended incorrect flow), the flow ends and it does not have a myResponse property.

It would be ideal if you can notify of such cases so the rest of the code can react accordingly.

Thanks for the suggestion. Need to think and design a generic and flexible solution for this request. There are several cases to consider.
