Goals:
- Improve upgrade experience: users should be able to gradually roll upgrades, with proper
canary deployments for Istio components. It should be possible to deploy a new version while keeping the
stable version in place and gradually migrate apps to the new version.

- More flexibility: the new installer allows multiple 'environments', allowing applications to select

    kubectl --namespace $NAMESPACE --overwrite=true label $KIND $RELEASE app.kubernetes.io/managed-by=Helm
