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
column names to be configured. This has the advantage that unnecessary
columns can be avoided, saving space.

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.

[CE backport] Parse and store multiple security reports of the same category

See merge request gitlab-org/gitlab-ce!30658

Parse and store multiple security reports of the same category

See merge request gitlab-org/gitlab-ee!14591

MergeReportsService merges several security report
POROs into one. This involves deduplicating
vulnerability occurrences that share the same
location, and at least one (identifier type,
identifier value) pair, not including CWEs since
CWE is not a identifier but rather a class of
vulnerabilities. First found occurrence wins.
Then, occurrences are sorted by severity (desc)
and then by compare key (asc).
