### Description In my company we use youtrack for issue tracking. Youtrack have issue ID in format `XYZ-123` where is `XYZ` is project (not gitlab project) and `123` number of issue in project. We have problem with regular expression for find and make link to external issue. Main goal is working link to youtrack from commit messages and merge requests. ### Proposal Create new issue tracker based on `IssueTrackerService` with specific regexp for select whole issue ID. Currect regexp is `%r{(?<issue>[0-9A-Za-z_]+-[0-9]+)}` ### Links / references https://www.jetbrains.com/youtrack/whatsnew/
