ErrorOr (SmallRye: GraphQL Client

```
public final class ErrorOr<T>
extends Object
```
Like an Optional, but if a value is not present, there is a List of GraphQLClientErrors instead. There can be the paradox situation that there is a value as well as errors, but this is what a GraphQL service could theoretically return!
