s7 endpoint config via environment variables

[YensDeFraeye-private]

Describe the bug

I'm trying to set the s7 node config via Environment Variables. In the config node, I'm setting the LOGO address via the ${env var} syntax, but it seems like it is not recognized.

To Reproduce

Steps to reproduce the behavior:

1. Add a new environment variable which stores the LOGO ip address
2. Add a new s7 endpoint config with the Address set as ${Environment var name}
3. Deploy

Expected behavior

I would expect the node to take the actual value from the environment variable and use that IP to connect.
