DATAREST-577 - Excerpt projections are now configured automatically.

Excerpt projections defined in @RepositoryRestResource had to be discoverable (i.e. located in a sub-package of the domain type). RepositoryRestMvcConfiguration now uses an newly introduced constructor of ProjectionDefinitionConfiguration that automatically registers all projects in the given ResourceMappings.
