Emphasize irreversibility in warning message when promoting labels and milestones
- We've had at least one report of a customer mistakenly promote milestones: https://gitlab.slack.com/archives/C0AR2KW4B/p1512661192000408.
- Let's update the warning message to be more explicit that you cannot reverse the action.
Current messages:
Change to:
- Promoting this milestone will make it available for all projects inside the group. Existing project milestones with the same name will be merged. This action cannot be reversed. Are you sure?
- Promoting this label will make it available for all projects inside the group. Existing project label with the same name will be merged. This action cannot be reversed. Are you sure?
