coordination #93668: [epic] Redesign Installation test modules
Implement simple start installation using client libyui-rest-api
Extract logic in start_install related to our YaST group and apply it with client libyui-rest-api.
Logic is the following:
- Click on Install on dialog 'Installation Settings'
- Handle Confirm Installation Popup
- Click on Install
Ensure working for ncurses and qt.
In 'start_install' there is more logic that we might consider in future: Autoyast, support server, upgrades, livecd, but for now we can leave it aside if not used in our job group.
