2.0

Bunch of temporal updates

* Added all the changelogs under the same component and remove the card
* Properly added UpdaterService as a class (not sure when I set it as object)
* Moved package name to co.aospa.hub to match current OTA package
* Only update notification and progress bar when percentage grows at least one integer
* Updated and fixed some stuff
