requests to the agent, causing the agent to submit a CSR to the configured CA (generally Istiod). For other configuration,
Envoy will send [ADS](https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/operations/dynamic_configuration#aggregated-xds-ads)
requests to the agent, which will be forwarded to the configured discovery server (general Istiod).
