Currently the `GeoServerInterceptor` can not handle WMS GetFeatureInfo requests querying layers from differing GeoServer namespaces, e.g. ``` QUERY_LAYERS=NS_1:layer1,NS_2:layer2 ``` The URI of the first detected Namespace is used, see [here](https://github.com/terrestris/shogun-core/blob/master/src/shogun-core-main/src/main/java/de/terrestris/shoguncore/service/GeoServerInterceptorService.java#L121) and [here](https://github.com/terrestris/shogun-core/blob/master/src/shogun-core-main/src/main/java/de/terrestris/shoguncore/service/GeoServerInterceptorService.java#L465).
