* Refactoring HOS folder structure Refactoring HOS folder structure: - Added some subfolders when needed (Following structure decided in private). - Added some `Types` folders when needed. - Little cleanup here and there. - Add services placeholders for every HOS services (close #766 and #753). * Remove Types namespaces
