to generate a new secret and push the updated certificate to Envoy. This ensures that we do not permanently watch certificates even after
Envoy has stopped requested them; if there are no subscriptions they update will be ignored. If Envoy later watches these certificates again,
a new one will be generated on demand.

#### Endpoints

Endpoints have an optimized code path, as they are by far the most frequently updated resource - in a steady cluster, this will often be the *only* change, caused by scale up/down.
