Missing support for a Dagger2 extension

[kerbymart]

The framework includes an extension for Guice for dependency injection, however, it lacks an extension for Dagger2.

Reflection-based dependency injection (DI) can impede the creation of a high-performance, native-image packaged module, such as an embedded Restlet server compiled using GraalVM.

You can find a proof of concept (POC) for using Dagger2 with Restlet by following this link:
