Improves add_timestamps_with_timezone helper

See merge request gitlab-org/gitlab-ce!30720

This improves the `add_timestamps_with_timezone` helper by allowing the

Fix pid providing for Prometheus

Closes #63870

See merge request gitlab-org/gitlab-ce!30474

Use relative worker identifier for metrics (instead of Process.pid) and
identify when Unicorn/Puma/Sidekiq is used.
Previously, it was assumed that all metrics are gathered from Unicorn
due to hardcoded implementation which was incorrect.

This adds `rugged_duration_ms` and `rugged_calls` fields to
`api_json.log` and `production_json.log`. This will make it easier to
identify performance issues caused by excessive I/O.
