The policy to use for the child workflow executions if this execution gets terminated by explicitly calling the TerminateWorkflowExecution action or due to an expired timeout.
The supported child policies are:
TERMINATE: the child executions will be terminated. REQUEST_CANCEL: a request
to cancel will be attempted for each child execution by recording a WorkflowExecutionCancelRequested event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event. ABANDON: no action will be taken. The child executions will continue to run.
