Adds time limit for change issues, reminder about incident issues
While we are generally being good with incident issues, I noticed today that we have >20 open change issues, most of which have not been updated in more than 5 days https://gitlab.com/gitlab-com/gl-infra/production/issues?label_name%5B%5D=change
this adds two changes to our triage-ops policy for change and incident issues:
- Incident issues left open for longer than 3 days without any activity will get a note reminder to the submitter, but leaves them open.
- Change issues left open for longer than 5 days without any activity will get a note reminder, and will automatically be closed. If owner of the issue wishes to, they can re-open.
