CNCF - Kuma: Active monitoring of Cross Zone communication

Description: Kuma is a modern Envoy-based service mesh that can run on every cloud, in a single or multi-zone capacity, across both Kubernetes and VMs. It is currently a CNCF Sandbox project. Because Kuma is heavily built with multi zones in mind it is needed for Kuma to provide a good level of observability of connectivity between these zones. This project aims to provide active monitoring of connections between each zone and create new apis to bubble up this information in the GUI and in our Grafana dashboards. This project goes from design to complete implementation, documentation and demonstration.
