Adds a valkey helm remote and allowlists the operator/exporter images so the
valkey-operator install in argocd-apps resolves everything through artifactapi.
- Add config/remote_helm/valkey.yaml proxying https://valkey.io/valkey-helm
- Add valkey to the virtual/helm member list
- Allow ^valkey-io/ on the ghcr remote (operator image ghcr.io/valkey-io/valkey-operator)
- Allow ^oliver006/redis_exporter on dockerhub (Valkey metrics exporter)
The k8up backup operator will be installed via ArgoCD, which pulls charts
through the artifactapi virtual helm proxy. That proxy resolves only the
remotes listed as members, so the upstream k8up repo must be registered.
- Add config/remote_helm/k8up.yaml pointing at https://k8up-io.github.io/k8up
- Register k8up as a member of the virtual helm repository
