related: #61452

Summary

This adds Helm chart support for exposing Flower with Kubernetes Gateway API HTTPRoute.

  • adds flower.httpRoute values, schema, template, tests, and docs;
  • routes the default backend to the Flower service on ports.flowerUI;
  • supports custom labels, annotations, hostnames, parentRefs, path settings, and full rules override;
  • fails fast when Flower Ingress and Flower HTTPRoute are both enabled.

API Server HTTPRoute support was already added in #67675. This PR covers the remaining Flower scope for #61452.

Validation

E2E screenshot through the Gateway API path:
61452_flower_workers

This was opened at http://flower.localhost:8888/workers while port-forwarding the Envoy Gateway dataplane service, so the request path was:

browser -> Envoy Gateway service -> Gateway listener -> Flower HTTPRoute -> airflow-flower service

You can attempt to backport this manually by running:

cherry_picker 02a956f chart/v1-2x-test

This should apply the commit to the chart/v1-2x-test branch and leave the commit in conflict state marking
the files that need manual conflict resolution.

After you have resolved the conflicts, you can continue the backport process by running:

cherry_picker --continue

If you don't have cherry-picker installed, see the installation guide.

@nailo2c could you do a manual backport of it to the 1.2x release line?
