These classes should be moved:

• info.magnolia.personalization.preview.parameter.PreviewParameterDefinition
• info.magnolia.personalization.preview.parameter.PreviewParameterConverter

The info.magnolia.personalization.preview.filter.PreviewFilter currently uses preview parameters defined in info.magnolia.personalization.PreviewAppModule but should rather use the one that will be defined in each info.magnolia.personalization.registry.TraitDefinition (where the name of the trait will also be used as previewParameterName (prefixed accordingly)). This mean injecting the info.magnolia.personalization.registry.TraitDefinitionRegistry.

Other tasks:

• TraitClass is defined still in both TraitDefinition and PreviewParameterDefinition. We need to get rid one of them.
• The same applies for name property.
• Duplicated code in PreviewParameterConverterServiceImpl vs PreviewFilter.
• TraitDefinition should probably have enabled property.
