The RestorablePackage class is used like a data structure class for the ChangedRPMPackagesController, which in turn, we can replace the logic between the two and merge them into a single RestorablePackage class, which will handle install/removal of packages. We don't need a second controller for now, if the backup controller can handle what this class is doing.

Making it generic to handle packages will be a huge win for how we backup and restore packages.

Acceptance Criteria

• Transform the RestorablePackage class in a RestorableChange class
• Merge the contents from ChangedRPMPackagesController and RestorablePackage together
• Move them to the packages module
