Move all support questions off the GitHub issue tracker
Created by: riyad
We should be stricter on closing support questions à la "i can't get GitLab to work here" in this issue tracker and move them entirely over to Google Groups. Only if it has been determined that it's really is a bug either in the code or in the docs, it should be allowed on the GitHub issue Tracker.
GitLab has become quite popular and especially after the 3.0 release there have been a lot of those questions (the issue count hovered in the 380 ranges for this release, while it was at about 280 for v2.9).
Also any persistent issue/pit-fall should get an appropriate check in the gitlab:app:status task. (see #2004)
