Summary 💡

Enable Calico's Whisker observability UI and its required Goldmane flow aggregator as defaults in the tigera/on-prem package, achieving feature parity with the Cilium hubble overlay. Neither component is instrumented for Prometheus in this version.

Relates: sighupio/distribution#504

Description 📝

The Cilium CNI option ships a hubble overlay that enables flow visibility (Hubble relay) and a web UI (Hubble UI on port 8081) by default.

Calico (via the Tigera Operator) provides equivalent functionality:

Feature Cilium Tigera
Flow aggregation Hubble relay Goldmane
Observability UI Hubble UI (port 8081) Whisker (port 8081)
Optional Ingress hubble-ui service whisker service
Enabled by default Yes This PR
