WorkflowExecutionCancelRequested event in the currently
running workflow execution identified by the given domain, workflowId,
and runId. This logically requests the cancellation of the workflow
execution as a whole. It is up to the decider to take appropriate

action fails. The associated event attribute's
cause parameter is set
