QA spec for Auto DevOps should use 10GB GKE disk

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

For customers with thousands of entries in the table, lookups for an
LDAP identity dominated the PostgreSQL statistics because of sequential
scans. We can speed this up by adding a partial index with the
extern_uid and provider.

Fix exception handling in Gitaly autodetection

Closes #65328

See merge request gitlab-org/gitlab-ce!31285

This improves the graphql test helpers, failing earlier and more
explicitly.

In SELinux, the file cannot be written, and `Errno::EACCES`, not
`Errno::ACCESS` is thrown.

Closes https://gitlab.com/gitlab-org/gitlab-ce/issues/65328

1. `page.getViewpoint()` now takes in JSON instead of an integer.
2. Promises are returned from loading and rendering tasks.

Use the Helm `--atomic` flag when deploying Review Apps

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.
