Description
I am trying to import a raster source into QGIS with SRS: EPSG:3109. See the error resulting from the following command:
$ gdal_translate --debug on "http://gps.digimap.gg/arcgis/rest/services/JerseyBaseMap/MapServer?f=json&pretty=true" JerseyBaseMapLayer.xml -of WMS HTTP: Fetch(http://gps.digimap.gg/arcgis/rest/services/JerseyBaseMap/MapServer?f=json&pretty=true) WMS: Did not get WKID HTTP: Fetch(http://gps.digimap.gg/arcgis/rest/services/JerseyBaseMap/MapServer?f=json&pretty=true) ERROR 4: `/tmp/file.dat' not recognised as a supported file format. GDALOpen failed - 4 `/tmp/file.dat' not recognised as a supported file format.

Upon further investigation, it appears that the error is raised due to this map server's JSON "spatialReference" values using a "wkt" key in favour of either "wkid" or latestWkid" keys. JSON on map servers using these latter type can be successfully parsed/translated.
The particular piece of code responsible appears to be the GDALWMSDatasetGetConfigFromArcGISJSON method - line 433 in the WMS driver here: https://github.com/etiennesky/gdal-netcdf/blob/master/gdal/frmts/wms/wmsdriver.cpp
What I don't understand is why this method does not also parse the value for a "wkt" key and translate that from various recognised formats (PROJ is used in the example I gave).
