Constify the usage of xdaq::ApplicationDescriptor

Laurent Petre requested to merge cleanup/gem-application into develop


This MR aims at an initial cleanup of the base GEMApplication class, focusing first on the proper constification of the xdaq::ApplicationDescriptor* pointers. In addition, the C++17 nested namespace definition is used in the GEMApplication header and all fields are taken into account in the GEMApplication::ScanInfo xDAQ bag.
