doozer: point reconciliation-PR upstream heuristic at quay-proxy.ci.registry.openshift.org

[ashwindasr]

Summary

resolve_upstream_from() in doozer/doozerlib/cli/images_streams.py computes the desired upstream FROM pullspec used by doozer images:streams prs open when opening/updating reconciliation PRs against component repos. When an image member entry has no explicit content.source.ci_alignment.upstream_image override, it fell back to a hardcoded heuristic pointing at registry.ci.openshift.org. This switches that heuristic to quay-proxy.ci.registry.openshift.org, keeping the same /ocp/{major}.{minor}:{image_name} path structure.

Scope is intentionally narrow:

• Only the heuristic fallback branch of resolve_upstream_from() is changed. The image_entry.stream and explicit ci_alignment.upstream_image branches are driven by ocp-build-data config and are unaffected.
• The downstream ci_build_root coordinate parsing is host-agnostic (rsplit on / and :) and needs no change.
• Other unrelated registry.ci.openshift.org references elsewhere in the codebase (imagestream mirroring in this same file, build_sync.py, promote.py, get_nightlies.py, sync_ci_images.py, rhcos.py, distgit.py, rebaser.py, and the shared REGISTRY_CI_OPENSHIFT constant) are out of scope and untouched.

Note: This is expected to be a temporary change. We may need to switch this heuristic back to registry.ci.openshift.org (or another host) once the underlying registry migration this is working around is complete.

Test plan

• Updated test_resolve_upstream_from_with_member_using_heuristic and test_resolve_upstream_from_with_member_using_payload_name in doozer/tests/cli/test_images_streams.py to assert against the new host.
• uv run pytest --verbose --color=yes doozer/tests/cli/test_images_streams.py -- 28/28 passed.

Summary by CodeRabbit

• Bug Fixes
  • Updated upstream CI image references to use the quay-proxy.ci.registry.openshift.org registry.
  • Improved compatibility when resolving upstream images from release payloads.

Walkthrough

The upstream image resolver now returns member pullspecs through quay-proxy.ci.registry.openshift.org, and two unit tests expect the updated registry prefix.

Changes

Upstream pullspec update

Layer / File(s)	Summary
Resolver output and test expectations doozer/doozerlib/cli/images_streams.py, doozer/tests/cli/test_images_streams.py	resolve_upstream_from uses the quay-proxy registry prefix, with heuristic and payload-name tests updated accordingly.
