Add file with prevented cherry-picks

This lists all commits marked tagged as bugfix or release
that where explicitly not cherry-picked. Possible reasons for this:

* commits from a branch that was also merged to the release
* commits from a branch where the merge was cherry-picked
* bugfixes for code new to master
* commits that where picked but are not recognized as such
