Update GeoServer Tutorial

[sdc50]

The GeoServer tutorial has some hard coded paths to GeoServer that make it hard to follow if you are using a different Geoserver configuration than that prescribed by the tutorial. It would be easy to make it more generic and just get the paths from the geoserver_engine.

in the map controller, rather than hard coding the wms url:

geoserver_layer = MVLayer(
            source='ImageWMS',
            options={
                'url': geoserver_engine.get_wms_endpoint(),
                'params': {'LAYERS': selected_layer},
                'serverType': 'geoserver'
            },
            legend_title=legend_title,
            legend_extent=[-114, 36.5, -109, 42.5],
            legend_classes=[
                MVLegendClass('polygon', 'County', fill='#999999'),
            ]
        )

In the home controller, rather than having a constant GEOSERVER_URI:

        if WORKSPACE not in workspaces:
            from urllib.parse import urlparse
            parsed = urlparse(geoserver_engine.public_endpoint)
            uri = f'{parsed.scheme}://{parsed.netloc}/{WORKSPACE}'
            geoserver_engine.create_workspace(workspace_id=WORKSPACE, uri=uri)

I would prefer for this to be:

        if WORKSPACE not in workspaces:
            uri = f'{geoserver_engine.base_url}/{WORKSPACE}'
            geoserver_engine.create_workspace(workspace_id=WORKSPACE, uri=uri)

But we'd first have to add a base_url attribute to the geoserver engine.

The only concern I have with this approach is that it implies that the URI needs to match the engine URL, which it does not. It just has to be a unique ID in URL form. This isn't a bad approach though and the nuance could be explained in a note box.
