Include the model name in topic notifications

Filtering at the model level is extremely useful as it permits efficient tracking of multiple providers using the same model. The model URI is required to ensure strict uniqueness, however the model uri is difficult to represent in topic syntax, and would need large amounts of escaping. The trade off is therefore to allow the model name to be used in the topic for rapid checking, with the filter being available for more precise matching if needed.

Implement model deletion in the Model Manager

The model manager API provides a deletion method, but this was not implemented. This commit implements deletion logic, which delegates to the Model Nexus. The Model Nexus:

1. Finds the Model
2. If found it deletes any and all providers using the model, then it deletes the model from its owning EPackage
3. If the EPackage is now empty of models then the EPackage is removed from the Model Nexus

The ModelImpl has also been updated to check the the model is still registered before allowing any action. This prevents deleted models from being used after they are deleted.

Add support for nullable data which should not create a resource

In some cases null is a valid value to return, but should not be used to initialize a resource. For example if a DTO contains some optional resources which may never be set for some providers, but will be set for others, and those resources may be null, then this was not previously possible

Reinstate final modifier for GenericDto

The EMF dto altered the GenericDto so that it could extend it. The GenericDto was intentionally final to prevent usage mistakes in the API. There are few fields and we should copy them.

Fix missing check in SetValueCommand

The UPDATE_IF_PRESENT logic would always run even if the data value was not null. This has been fixed and regression tests added for all NullAction behaviours.
