Proposal: Setting to prevent self-applying MR review suggestions

Problem to Solve

If the approval setting prevent approval by users who add commits is enabled, any MR reviewer or maintainer who applies their own suggestion will no longer be able to approve or merge the MR. An organization may want to prevent maintainers from applying their own suggestions and accidentally removing their ability to approve. There may be other compliance reasons for wanting to prevent someone from applying their own suggestion.

Possible Solutions

• A project or group level setting that, when enabled, prevents someone from applying their own suggestion.
• A warning/confirmation when someone is about to apply their own suggestion and it would remove their ability to approve or merge the MR.
