[I] [apisix] Standalone API driven mode tries to connect to etcd [apisix-helm-chart]

   I have the following config:
   
   ```
   apisix:
     # standalone api driven mode: enable etcd free configuration via ingress-controller
     # taken from https://apisix.apache.org/docs/apisix/deployment-modes/#api-driven
     deployment:
       # mode: standalone this runs  `ln -s /apisix-config/apisix.yaml /usr/local/apisix/conf/apisix.yaml`
       role: traditional # deploy dataplane and control plane in the same pod
       role_traditional:
         config_provider: yaml
   
   etcd:
     enabled: false
   
   ...
   ```
   
   Everything is working fine. However, apisix logs are full of this error:
   
   ```

   ```
   
   Why is apisix trying to connect to etcd in standalone mode?
   
   After having a look at the deployment.yml of the chart I noticed that the `etcd` config is only omitted from the config map when `mode: standalone`. However in api driven  standalone mode, we have `mode: traditional`:
