Make service and app labels homogeneous across arnold applications

[madmatah]

Feature Request

Is your feature request related to a problem or unsupported use case? Please describe.

By convention, our kubernetes services have service and app labels.
They should be consistent with the directory structure.

I.e. objects declared in apps/my-app/templates/services/my-service should have the following labels :

  app: my-app
  service: my-service

This convention is not applied homogeneously across arnold applications.

Describe the solution you'd like

Check all arnold applications to apply this convention.

Here is a first list of "suspects" service labels :

$ for a in apps/* ; do app=$(echo $a | cut -d/ -f2); for s in "apps/$app/templates/services/"* ; do svc=$(echo "$s" | cut -d/ -f5); grep -R "service\: " "apps/$app/templates/services/$svc" | grep -vE "service: [\"]?$svc[\"]?" | grep -vE "[^[:space:]]+service:" | grep -v "{{ service_variant }}" ; done ; done
