GeoNode tries to access tabular data via GWC

[ridoo]

As tabular data is not spatial and not available via GWC. GeoServer is throwing exceptions when requesting GeoWebCache REST API:

geoserver4geonode_datapackage  | 14 Jun 11:15:25 ERROR  [geoserver.rest] - Unknown layer: geonode:horizon_data
geoserver4geonode_datapackage  | org.geowebcache.rest.exception.RestException 404 NOT_FOUND: Unknown layer: geonode:horizon_data
geoserver4geonode_datapackage  |        at org.geowebcache.rest.controller.GWCController.findTileLayer(GWCController.java:45)

GeoNode tries to create WMS thumbs (see this issue) , e.g.

• thumbs/thumbnails.py: create_thumbnail()
• GenericWMSBackground: fetch() is not imported anywhere (in the code there are some hints to Slippy Maps -- not sure, but I have the impression, this is some legacy code here)

GeoServer still logs a Warning when adding a non-exposable layer (no geometry).

@mwallschlaeger @specka Unfortunately, I do not see any way to avoid this without touching GeoServer, so we should leave it as is.

@ridoo i agree, we an keep this issue still open
