Holds information about /META-INF/services and /META-INF/inhabitants for a Module.

A Service implementation is identified by the service interface it implements, the implementation class of that service interface and the module in which that implementation resides.

Note that since a single ModuleDefinition is allowed to be used in multiple Modules, this class may not reference anything Module specific.
