// AddPodToMesh adds a pod to mesh by
// 1. Getting the netns
// 2. Adding the pod's IPs to the hostnetns ipsets for node probe checks
// 3. Creating iptables rules inside the pod's netns
// 4. Notifying ztunnel via GRPC to create a proxy for the pod
//
// You may ask why we pass the pod IPs separately from the pod manifest itself (which contains the pod IPs as a field)

## Proxy Configuration

Istiod's primary role - and most code - is to dynamically configure proxies (Envoy sidecars and ingress, gRPC, ztunnel, and more). This roughly consists of 3 parts:
1. Config ingestion (inputs to the system)
1. Config translation
1. Config serving (XDS)
