Localized variants via site filtered endpoints are configurable

The concept of a site filtered GraphQL endpoint prevents, that related content objects of a filtered content, not belonging to that site, can be retrieved over that endpoint. This behaviour may become unhandy for some special cases, e.g. localized variants or derived sites.

In order to overcome this limitation, the new configuration property ' caas.site-filter-config-properties.excluded-field-names ' was introduced. The property takes a collection of field names and defaults to " localizedVariant ", " localizedVariants " and " derivedSites ".

The default configuration now permits, that localized contents belonging to a related site can be retrieved, although a site filter is used. If neccessary, additional fields, e.g. 'pictures' can be added, if linked pictures belong to another site.

See the Deployment Manual for details.
