Refactoring HOS folder structure (#771)
* 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
