Get started with Istio - add non mTLS working before Peerauth

[find-arka]

Under "Securing Communication Within Istio" it might be worth showing that from sleep pod in default NS we are able to curl the web-api pod before we create the PeeerAuth

• Moving the following up &

kubectl apply -n default -f sample-apps/sleep.yaml

• Adding a before and after of the same command might be useful:

kubectl exec deploy/sleep -n default -- curl http://web-api.istioinaction:8080/
