  * In practice, this largely means that references are fully qualified in the API. IP Addresses (generally) have a network associated with them, node names have a cluster associated with them, etc.

See `istio/manifests/charts` for details about the new charts and why they were created. Briefly, the new charts
are intended to support production ready deployments of Istio that follow best practices like canarying for upgrade.

## Terminology

   1. The most common method (pictured above) is to sign a new certificate by calling the configured CA. Typically, this is Istiod.
   1. If the certificate is not yet expired, the `SecretManager` also can return a cache response. In practice, this would
       only happen in cases where Envoy were to re-request a resource, which is fairly rare.
   1. `SecretManager` can also read certificates from files. When this is configured, no CA client is used.
