Feature Request: Environment variable not recognized in .ini file

[toporek3112]

Describe the bug
When trying to set the password in the .ini file in the [/settings/default] section with an environment variable the value of the variabel is not configured. I am trying to deploy the client in a Kubernetes cluster running as a pod. In Kubernetes it is good practice to mount sensetive data from a secret.

To Reproduce
Steps to reproduce the behavior:

1. Set environment variable e.g export SNI_PASSWORD="<sha256value>"
2. Run client with following config

        [/settings/default]
        password = "${SNI_PASSWORD}"

Expected behavior
I would expect that the password would be the values of the environment variable

Those "macros" in the ini file are not environment variables. They can be used to do cross references or access path variables as described here: https://omd.consol.de/docs/snclient/configuration/#macros

But might be a good idea to add support for environment variables as well.
In case of the password, it is not really necessary, because you can use encrypted passwords.

I see. Thank you for the response and yes I think it would be a good idea to add support for env variables since its the go to method when deploying stuff to kubernetes. But jfyi. I found workaround by using postStart Hooks like this

command:
  - /bin/sh
  - -c
  - sleep 5s && snclient server
lifecycle:
      postStart:
        exec:
          command:
            - /bin/sh
            - -c
            - >
              HASH=$(snclient hash "$SNCLIENT_PASSWORD" | awk -F': ' '/hash sum/ {print $2}');
              echo -e "[/settings/default]\npassword = $HASH" > /etc/snclient/password.ini

and in the main ini file include the new file

[/includes]
local = /etc/snclient/password.ini
