Feature request: automatic Gitlab issues for failed/unstable builds

## Feature request: automatic Gitlab issues for failed/unstable builds

### Context
- not applicable

### Problem description

For GitHub, there is a plugin allowing the automatic creation of issues when a Jenkins build fails or becomes unstable. A similar functionality in this plugin would be nice.

Potential features:
- Create issue when a build becomes anything other than stable
- Allow specification of a template for the issue (body and title)
- Allow inclusion of a link to the 'offending' commit that triggered the build status change
- Allow selection of assignee to be configured to either the project own or the committer
- Allow tagging the owner/committer in the body
- Allow automatic closure of such issues once the build goes back to stable
