ArgumentsAggregator (JUnit 5.2.0-M1 API)

```
@API(status=EXPERIMENTAL,
     since="5.2")
public interface ArgumentsAggregator
```
ArgumentsAggregator is an abstraction for the aggregation of arguments provided by an ArgumentsProvider for a single invocation of a @ParameterizedTest method into a single object.
An ArgumentsAggregator is applied to a method parameter of a @ParameterizedTest method via the @AggregateWith annotation.
The result of the aggregation will be passed as an argument to the @ParameterizedTest method for the annotated parameter.
A common use case is the aggregation of multiple columns from a single line in a CSV file into a domain object such as a Person, Address, Order, etc.
Implementations must provide a no-args constructor.

5.2
