Extend black-listing/white-listing check to support Interfaces

[ikkisoft]

It may be interesting to allow users to specify interfaces and block/allow classes implementing those interfaces.

It would require to modify the black-listing/white-listing check, adding some logic around public Class<?>[] getInterfaces().

Not sure if we want to add a specific notation for interfaces in the config file, or simply add those items as the current class names.

Also, a class may implement multiple interfaces thus we need to figure out a good strategy.
