Implement possibility to save arbitrary number of object parameters in IFactory::registerItem

Something like:

registerItem("CylinderSpecial",
              create_new<FormFactorCylinder>,
              "Special version of cylinder",
              2.0, 3.0);

this will allow to create objects like
auto ff = create("CylinderSpecial")
without specifying cylinder parameters.

Refactoring should involve variadic templates and tuples to make it possible.

This will allow further simplification of functional test machinery.

• StandardTestService+StandardTestCatalogue will go in the favor of unique TestService.
• Class IRegistry can be thrown away
• TranslationTests, SampleComponents can be simplified
