RPM Support

In pulp 2.7, if a group was uploaded (via the API's /import_upload/) and it already existed, it was updated.

In pulp 2.10, the update doesn't happen anymore.

The problem is in the yum importer, in _handle_group_category_comps:

    else:
        # uploading a package group, package category or package environment
        unit_data = {}
        unit_data.update(metadata or {})
        unit_data.update(unit_key or {})
        try:
            unit = model_class(**unit_data)
        except TypeError:
            raise ModelInstantiationError()

        try:
            unit.save()
        except NotUniqueError:
            unit = unit.__class__.objects.filter(**unit.unit_key).first()

        repo_controller.associate_single_unit(repo, unit)

Notice that, if the unit exists (and fails to save), the existing unit is never updated.
