At a high level, the Istio agent acts as an intermediate proxy between Istiod and Envoy. This is done
at two levels. For distributing workload certificates, Envoy will send [SDS](https://www.envoyproxy.io/docs/envoy/latest/configuration/security/secret)
requests to the agent, causing the agent to submit a CSR to the configured CA (generally Istiod). For other configuration,
