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

[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).

Previously `start_sha` was intercepted on the frontend to create the
correct branch in a separate API call. Now that the commits API supports
the `start_sha` parameter directly this workaround is not needed
anymore.
