I know, the version looks wierd. But we needed to version our
chart without making it terribly confusing for end users and also
sticking to semver.

Due to changes in the UI of the Istio chart we need to add minimum
Rancher versions to ensure that the Istio chart will display its UI
elements correctly within Rancher.

Note:
See https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/
- PSP is introduced in policy apigroup in 1.10, and removed from extensions apigroup in 1.16.
- DaemonSet, Deployment, StatefulSet, and ReplicaSet migrate to apps in 1.9, and no longer be served from extensions in 1.16
- Ingress is migrated to networking.k8s.io in 1.14, and will be removed from extensions in 1.18

Formerly, it is accessible by authenticated users.
Now, it is accessible by cluster owners and authorized users/groups.

Change all the repository in the istio to use rancher repo to pull the
image.

  * add istio and certmanager CRDs
  * add rancher system default registry config
  * add rancher proxy to the Grafana, Prometheus, Kiali and Tracing
  * remove not used demo values.yaml files and serviceGraph(deprecated)
