Automated QA failure issues - consider how to handle multiple related issues

Sometimes we'll report multiple failing tests in a single issue. For example, if several test fail in the same way, or there are multiple failures that seem related in the same spec file.

One recent case is this: gitlab-org/gitlab#273007 (closed)

They all seem to be failing for the same reason, so it's reasonable to group them together.

Unfortunately, the automation that creates failure issues creates separate issues in a case like this. Instead of one issue there would be ten.

We should find a way to have only one issue to manage.
