Enhance test-related classes as loaded

[sebersole]

Is there an existing extension point in JUnit 5 that would allow me to hook into the loading of test related classes, Java agent style?

The classes to be enhanced are specified by extension annotations. E.g.

@DomainModel( annotatedClasses = {SomeClass.class, AnotherClass.class} )

Here, I'd want SomeClass and AnotherClass to be enhanced as they get loaded.
