Edit labels to guest
Proposal
It would be great if guests could edit labels on issues, especially if the editor is the same user as the creator.
Our users usually have different roles on each project (on some projects they are guests because they must not see the source code of our software, on others where we store customers' configuration they are maintainers). It happens that a user forgets to add specific labels, or wants to edit because the issue changed its original nature, and we have some skilled guest users that can do that without having to wait for the maintainers of the project.
