Native image compilation requires a "reflect-config.json" file for each package containing the full canonical name of of "declared types".

Possible solution
1) inside PMMLCogitoCodegen: iterate over all the sources in rulesSourceMap and look for a "org.drools.core.factmodel.GeneratedFact" (it mark the declared types)
2) collect the full name of such sources (should be the key in the rulesSourceMap)
3) Modify KogitoPakageSources to expose `new GeneratedFile("META-INF/native-image/" + pkgModel.getPathName() + "/reflect-config.json", reflectConfigSource(pojoClasses));` as static method
4) invoke that method to create the reflect-config.json files
5) add this files as resources to the generetad file list
