[FLINK-4751] [futures] Add thenCombineAsync function to Flink's futures
The `thenCombineAsync` method allows to combine two futures and apply a
`BiFunction` on
the results of both futures. The `BiFunction` is only applied after both
futures have
completed.
```
Future<Left> left = ...
Future<Right> right = ...
Future<Result> resultFuture = left.thenCombineAsync(
right,
new BiFunction<Left, Right, Result>() {....},
executor);
```
