Verify counts time out in usage ping for GitLab.com
I tested https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/21523 in a production console, and we got -1 (a statement timeout) for these fields:
ci_builds
ci_internal_pipelines
If these are counting the whole table, we can use approximate counts. Otherwise we need to come up with another fix, or we won't get data from GitLab.com for these fields.
@erushton I'll leave it up to you to schedule this.
