Previously this was only enabled for optional arguments (i.e.
those with default values). Enabling them for all arguments
allows for more readable PyQGIS code, and there seems no
downside given that we already have this support partly enabled.
The consequence of this change is that when 3.0 API is frozen
the freeze must also include the naming of function arguments,
since that's effectively now part of public API.
- Add server exception base class
- Enable per service exception definition
- Handle QgsException gracefully (error 500)
- Handle OGC exception versioning
* layerFilterExpression
Return an additional filter, used in
WMS/GetMap, WMS/GetFeatureInfo, WFS/GetFeature to filter the features
* layerFilterSubsetString
Return an additional the subset string (typically SQL) filter.
Faster than the layerFilterExpression but not supported on all the
type of layer
* layerPermissions
Change the rights on the layer per user (known by the plugin)
Concern rights: publish, insert, update, delete.
Mostly used in WFS/Transaction, and the publish in all requests.
* authorizedLayerAttributes
Be able to show some attributes only for a subset of user
Used in: WMS/GetFeatureInfo, WFS/GetFeature
* allowToEdit
Be able to don't allow to edit a particular feature, in our case base
on the Geometry
Used in: WFS/Transaction
* cacheKey
Cache key to used to create the capabilities cache, "" for no cache,
shouldn't contains any "-", default to ""
