Issue

• The following Drools 6 API code help users to load rule asset (like DRL) in KieBuilder so that KieModule could be built and deployed to KieRepository.

    public static KieContainer createKieContainerForProject() {
        KieServices kieServices = KieServices.Factory.get();
        // Create a module model
        KieModuleModel kieModuleModel = kieServices.newKieModuleModel();

        // Base Model from the module model
        KieBaseModel kieBaseModel = kieModuleModel.newKieBaseModel( "KBase" )
                .setDefault( true )
                .setEqualsBehavior( EqualityBehaviorOption.EQUALITY)
                .setEventProcessingMode( EventProcessingOption.STREAM );                

        // Create session model for the Base Model
        KieSessionModel ksessionModel = kieBaseModel.newKieSessionModel( "KSession" )
                .setDefault( true )
                .setType( KieSessionModel.KieSessionType.STATEFUL )
                .setClockType( ClockTypeOption.get("realtime") );

        // Create File System services
        KieFileSystem kFileSystem = kieServices.newKieFileSystem();

        File file = new File("/opt/brmsrepo/src/main/resources/rules/Test.drl");
        Resource resource = kieServices.getResources().newFileSystemResource(file).setResourceType(ResourceType.DRL);
    kFileSystem.write( resource );       

        KieBuilder kbuilder = kieServices.newKieBuilder( kFileSystem );
        // kieModule is automatically deployed to KieRepository if successfully built.
        kbuilder.buildAll();

        if (kbuilder.getResults().hasMessages(org.kie.api.builder.Message.Level.ERROR)) {
            throw new RuntimeException("Build time Errors: " + kbuilder.getResults().toString());
        }
        KieContainer kContainer = kieServices.newKieContainer(kieServices.getRepository().getDefaultReleaseId());
        return kContainer;
    }

However there are some questions regarding the code flow.
1) The ksessionModel that is created is never used. Where and how to use it?
2) Where else the KBase name will be used after creating kieModuleModel.newKieBaseModel( "KBase") ?
3) The kFileSystem.write( resource ); is used in the aforementioned example, but the following piece of code seems to be also there to do the same job.

KieFileSystem kFileSystem = ...
kFileSystem.write( "src/main/resources/TestDRL.txt", kieServices.getResources().newInputStream Resource( drlStream )
.setResourceType(ResourceType.DRL) );

In Drools 5 it was required to type the DRL file whereas here there are 2 parameters available, src/m ain/resources/TestDRL.txt and a Resource to the file as shown above. Which scenario is appropriate for using the src/main/resources/TestDRL.txt way ?
4) What is the equivalent in Drools 6 for the old KnowledgeBase API used in Drools 5?
