Add upgrade step that removes AtD settings

[reinhardt]

See plone/Products.CMFPlone#3765

Is this the right place to add the upgrade? Should I create a new version?

Should I add a towncrier entry?

@reinhardt thanks for creating this Pull Request and helping to improve Plone!

TL;DR: Finish pushing changes, pass all other checks, then paste a comment:

@jenkins-plone-org please run jobs

To ensure that these changes do not break other parts of Plone, the Plone test suite matrix needs to pass, but it takes 30-60 min. Other CI checks are usually much faster and the Plone Jenkins resources are limited, so when done pushing changes and all other checks pass either start all Jenkins PR jobs yourself, or simply add the comment above in this PR to start all the jobs automatically.

Happy hacking!

Missing a changelog entry. Jenkins is currently running, so let's not bother at this moment. Once it is finished, we can merge all. And then I can add the changelog entry directly on master.

Remind me if I forget. :-)

There's already “Added upgrade to 6103, Plone 6.1.0a4.”: https://github.com/plone/plone.app.upgrade/blob/master/news/6103.internal

Does that count?

No, I like to be more specific. :-)
I added a snippet in commit d6d277f.
