    server: Move knowledge of supported profiles
    
    Query the supported profiles (all, upload) from the MediaServerPlugin,
    provide a default implementation that does return everything from the
    profiles supported by the MediaEngine.
    
    Note: This is done via properties in this slightly complicated manner to not
    break ABI this late in the cycle. Ideally it should be abstract/virtual
    properties or abstract/virtual functions.
