Notify when blocking issues are resolved
There are many times where one issue is blocked on another issue. Sometimes it can be months before the blocking issue is resolved.
At the moment, we used blocked to indicate that an issue cannot proceed, and rely on a comment to tell us why.
Proposal
It would be great if there was a way to say that an issue is blocked by another issue (or set of issues), and supply the blocking issue numbers. Then when the blocking issues are resolved, those watching the blocked issue are notified.
For Example
This issue: https://gitlab.com/gitlab-org/gitlab-ee/issues/5260 is blocked as shown here: https://gitlab.com/gitlab-org/gitlab-ee/issues/5260#note_154009654
In order to know when I can continue, I need to subscribe to the related MR and watch for the merge to happen.
