Add FeatureListURL in QGIS WMS Server GetCapabilities Request

When a layer is published as a WFS FeatureType, WMS GetCapabilities
Answer containing a FeatureListURL. The FeatureListURL contains an

GRASS fixes: remember last mapset, update layer list in tools if a layer is added/removed
Fix crash when authentication fails. Fix #7913

Like WMS services, users can configure an advertised URL for WFS
services.
If no advertised WFS URL is specified, QGIS-Server looked at the
advertised WMS URL.

Add GetContext request to QGIS WMS Server

This non standard request retruns the QGIS project as an OWSContext
document version 0.3.1.
This request gives more interoperability to QGIS Server that can be
directly used in client supporting OWSContext as config file.
This function has been funded by Ifremer.
