Enable RuboCop syntax linting in haml-lint

Closes #64753

This allows the chaos endpoints to be invoked in Sidekiq so that this
environment can be tested for resilience.

The refactor consists in:
- Better scopping preconditions and the test definition
- Removing a variable that was being used in a single palce, and
use the string directly instead.

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

A helper for removing the columns is also provided, to be used in the
`down` method of migrations.

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.
