When using yast software manager, there should be the option of discarding all
changes without having to quit and restart it. currently it seems like the only
way of doing this is to open up an installation summary and then select keep on
the changed packages, which isn't as intuitive or easy to get to for a user
than simply having an entry in options that says reset changes if the user
changes its mind and wants to start fresh.

Reproducible: Always
