   the `SecretManager` to Envoy, without much business logic. For each resource requested by Envoy, the SDS server
   will call `SecretManager.GenerateSecret(resourceName)`
1. When `GenerateSecret` is called, the `SecretManager` is expected to return a new certificate. This can occur in a few ways.
   1. The most common method (pictured above) is to sign a new certificate by calling the configured CA. Typically, this is Istiod.
