Because this code is executed before the application **starts** taking requests, and right after it **finishes** handling requests, it covers the whole application **lifespan** (the word "lifespan" will be important in a second 😉).

- will send all the existing payloads (that it has in its cache) to the ztunnel using AddWorkload message.
- the ztunnel will send an ack for each payload (which the CNI will wait for before sending the next one).
- when the CNI finishes sending the content of its current cache, a SnapshotSent message will be sent.
- the ztunnel will then remove any entries from its cache that were not sent up to this point (as these entries do not exist in the CNI
