4) `gateways` charts install a load balancer with `ingress` and `egress`.

Ingress secrets and access should be separated from the control plane.

```console

            --set policy.enable=false \
            --set global.istioNamespace=istio-master
```

### Gateways

A cluster may use multiple Gateways, each with a different load balancer IP, domains and certificates.

Since the domain certificates are stored in the gateway namespace, it is recommended to keep each
gateway in a dedicated namespace and restrict access.

- the new chart uses the default namespace service account, and doesn't require
additional RBAC permissions.

- simplified label structure. Label change is not supported on upgrade.

- for 'internal load balancer' you should deploy a separate gateway, in a different
namespace.

All ingress gateway have a "app:ingressgateway" label, used to identify it as an
ingress, and an "istio: ingressgateway$SUFFIX" label of Gateway selection.
