  **Improved** Gateway certificates to be read and distributed from Istiod, rather than in the gateway pods.
  This reduces the permissions required in the gateways, improves performance, and will make certificate reading
  more flexible in the future. This change is fully backwards compatible with the old method, and requires no changes
  to your cluster. If required, it can be disabled by setting the `ISTIOD_ENABLE_SDS_SERVER=false`
  environment variable in Istiod.
