Merge given monos into a new {@literal Mono} that will be fulfilled when all of the given {@literal Monos}
have produced an item, aggregating their values into a {@link Tuple2} and delaying errors.
If a Mono source completes without value, the other source is run to completion then the
resulting {@link Mono} completes empty.
If both Monos error, the two exceptions are combined (as suppressed exceptions on a root exception).
