> cancel_query_and_validate_state is a helper method used to test query
> cancellation with concurrent fetch. It is still use beeswax client by default.
> Ideally, we should change this test to use HS2 protocol by default. But
> ImpylaHS2Connection, a wrapper of Impyla, is not thread safe. We need to
> relax this test method in several way:
> # Implement HS2_OPERATION_RETURN_IF_ERROR. Similar like
> HS2_RETURN_IF_ERROR, but additionally set operationState to
> TOperationState::ERROR_STATE.
> # Make client operation such as execute_async, fetch, cancel,
> get_runtime_profile mutually exclusive.
> # Do not attempt to fetch if there is a debug action set to prevent it (ie.,
> wait GetNext indefinitely).
> # Do not attempt to fetch if query handle is error right after execute_async.
