Add a method RequirementAddOn.add_module(Architecture, CapellaModule) and RequirementAddOn.remove_module(Architecture, CapellaModule)

[ylussaud]

We need to add the concept of Architecture to the Capella API.

The the implementation should look like this:

architecture.get_java_object().getOwnedExtensions().add(capellaModule.get_java_object())

architecture.get_java_object().getOwnedExtensions().remove(capellaModule.get_java_object())
