Removes capabilities document.

Returns cached capabilities document (or 0 if document for configuration file not in cache)

Inserts new capabilities document (creates a copy of the document, does not take ownership)
static void logMessage(const QString &message, const QString &tag=QString(), Qgis::MessageLevel level=Qgis::MessageLevel::Warning, bool notifyUser=true)
Adds a message to the log instance (and creates it if necessary).
