Spinnaker currently cannot discover or cache GCP Regional External HTTP(S) Load Balancers. When these L7 regional load balancers are created in GCP and attached to MIGs, Clouddriver fails to find them and pipelines cannot reference them. Only global HTTP(S) LBs and regional TCP/UDP network LBs are supported today.

Impact

This blocks regional architectures that require L7 load balancing. Customers must use global LBs, manage LBs outside Spinnaker, or implement manual workarounds.

Expected Behavior

Spinnaker should detect, cache, and allow pipelines to attach to regional external HTTP(S) load balancers.
