DATAMONGO-1899 - Export composable repositories via CDI.

We now export composable repositories through our CDI extension. Repositories can now be customized either by a single custom implementation (as it was before) and by providing fragment interfaces along their fragment implementation.

This change aligns CDI support with the existing RepositoryFactory support we provide within a Spring application context.
