👷 do not rely on hardcoded list of DCs

[thomas-lebeau]

Motivation

We want to avoid hardcoding the list of datacenter in the release process. This will remove the need for creating a PR for new DCs.

For this we discover the list of DC and their corresponding site using ddtool Runtime Metadata Service.

PR stacked on top of #3973

Changes

• Refactor a bit to normalize usage of datacenter vs uploadPath and try to make things more clear
• Added unit tests for deploy-prod-dc script.
• removed siteByDatacenter in favor of a ddtool command

Todos

• install ddtool on the CI (or find another way) used Runtime Metadata Service
• fix upload-source-maps test failing. for some reason the mock seems to initialize too late

Test instructions

Keep private regions in the deploy pipeline

Filtering getAllMinorDcs() to exclude pr* means the minor-dcs group no longer includes private regions, but both deploy pipelines still only invoke deploy-prod-dc.ts with DATACENTER: minor-dcs and don’t add a private-regions step. As a result, private regions like prtest00/prtest01 won’t receive deployments anymore unless a new pipeline step is added or they’re re‑included here.
