  * 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)

Add globalRegistryMode to enable deploying the Harbor as a global
registry in Rancher. It use the same domain as Rancher server in
ingress rules, and use the same tls-rancher-ingress secret for TLS.

**Solution:**
Add `container_name!=""` into the expression
