Document: How to use with Istio

[haf-afa]

These env vars:

        env:
        - name: ISTIO_QUIT_API
          value: http://127.0.0.1:15020
        - name: ENVOY_ADMIN_API 
          value: http://127.0.0.1:15000

works on istio 1.3.3

But without ENVOY_ADMIN_API, it hangs. Note its port, which is different from the README's port of Envoy's admin API.

Isn't this covered in the 1.3 and higher section of the README?

readme says that only one of these vars is important but both are needed.

Hi team, may I ask other than adding in environment vars like this:

env:
            - name: ENVOY_ADMIN_API
              value: http://127.0.0.1:15000
            - name: SCUTTLE_LOGGING
              value: "true"
            - name: ISTIO_QUIT_API
              value: http://127.0.0.1:15020

Anything else I need to add to make scuttle stop istio? Since right now I dont see it is stopping istio and I dont see any logs. Thank you!!
