Setup app settings for remote debugging node and python functions on linux dedicated apps

cc @mhoeger @ColbyTresness

Following app settings, need to be set when APPSVC_REMOTE_DEBUGGING is set to true
```
languageWorkers__node__arguments = --inspect=0.0.0.0:5858
APPSVC_TUNNEL_PORT = 5858

```
@ahmelsayed - Do you have any ideas on how to achieve this?

Start by tracing how APPSVC_REMOTE_DEBUGGING is handled for Linux dedicated apps and where app settings are applied. Verify the node debugging arguments and APPSVC_TUNNEL_PORT behavior for both node and Python functions; done means the requested settings are applied when remote debugging is enabled.
