Port deprecated KCMultiDialog methods & embed json metadata in KCM
This KCM will have to get installed installed in the new plasma namespace eventually. But considering that this app is part of the release service, we should not depend on changes in a not yet released Plasma version.
Task: https://phabricator.kde.org/T14501
Depends on frameworks/kcmutils!68 (merged)
