In the transition phase, the Istio sidecar injector policy is configured as "disabled" when installing Istio. So the sidecar injector will not inject the sidecar into pods by default. Add the `sidecar.istio.io/inject annotation` with value `true` to the pod template spec to enable injection.

We also need to add "http" prefix to port name to leverage some advanced Istio features, such as distributed tracing.
