When all charts are migrated, we can:
* discontinue maintenance for the "envoy-tls-local-proxy"
* remove "envoy-tls-local-proxy" from git
* maybe remove the images as well (so they are not used by accident)?
Charts using v0.1 _tls_helper:
[x] blubberoid
[x] citoid
[x] cxserver
[x] wikifeeds
[x] chromium-render
[x] mobileapps
[x] recommendation-api
Special charts that don't use the common helper:
[x] changeprop/templates/deployment.yaml: image: {{ .Values.docker.registry }}/envoy-tls-local-proxy:{{ .Values.tls.image_version }}
[] eventgate/templates/_tls_helpers.tpl: image: {{ .Values.docker.registry }}/envoy-tls-local-proxy:{{ .Values.tls.image_version }}
[x] eventstreams/templates/_tls_helpers.tpl: image: {{ .Values.docker.registry }}/envoy-tls-local-proxy:{{ .Values.tls.image_version }}
To figure out if `envoy-tls-local-proxy`is still running somewhere:
```
kubectl get pods --all-namespaces -o go-template --template='{{range .items}}{{$n := .metadata.name}}{{range .spec.containers}}{{$n}}{{":\t"}}{{.image}}{{"\n"}}{{end}}{{end}}' | grep envoy-tls-local
```
