[FEATURE][SERVER] GetFeature with an other Geometry

This commit completes 'GetFeature without geometry' e3a832c The GeometryName parameter can be used to get the extent or the centroid as the geometry. This Feature can be used to have a lighter gml document. The extra parameter GeometryName can be: * None * Extent * Centroid
