This change is a fairly straightforward refactor to extract the tracing
and correlation-id code from the gitlab rails codebase into the new
LabKit-Ruby project.

The corresponding import into LabKit-Ruby was in
https://gitlab.com/gitlab-org/labkit-ruby/merge_requests/1

The code itself remains very similar for now.

Extracting it allows us to reuse it in other projects, such as
Gitaly-Ruby. This will give us the advantages of correlation-ids and
distributed tracing in that project too.

Bring back Rugged implementation of ListCommitsByOid

This brings back changes in
https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20432.

For users using Gitaly on top of NFS, accessing the Git data directly
via Rugged may be faster than going through than Gitaly. This merge
request introduces the feature flag `rugged_list_commits_by_oid` to
activate the Rugged method.

For one customer, we saw that ListCommitsByOid was the second highest
used endpoint that may be causing increased load.

Revert "Merge branch 'boards-stylelint' into 'master'"

Closes gitlab-ee#11200

See merge request gitlab-org/gitlab-ce!27452

This adds the backtrace to a table to show exactly where the Gitaly call
was made to make it easier to understand where the call originated.

This change also collapses the details in the same row to improve the
usability when there is a backtrace.

People who prefer plain text email also might prefer the raw job log
files. So include the link directly to there.
