QA spec for Auto DevOps should use 10GB GKE disk

See merge request gitlab-org/gitlab-ce!31266

scans. We can speed this up by adding a partial index with the
extern_uid and provider.

See merge request gitlab-org/gitlab-ce!31238

1. The output isn't great. It can be hard to find hotspots and, even
   when you do find them, to find why those are hotspots.
2. It uses some jQuery-specific frontend code which we can remove now
   that we don't have this any more.
3. It's only possible to profile the initial request, not any subsequent
   AJAX requests.
