hos: Cleanup the project (#2634)
* hos: Cleanup the project

Since a lot of changes has been done on the HOS project, there are some leftover here and there, or class just used in one service, things at wrong places, and more.
This PR fixes that, additionnally to that, I've realigned some vars because I though it make the code more readable.

* Address gdkchan feedback

* addresses Thog feedback
