Prosody extraConfig prints readFile functions wrong

[gianmarcogg03]

Describe the bug

In my Prosody configuration I have set a secret for a module that goes like this:

turn_external_secret = "secretgoeshere"

However, if I put a builtins.readFile function to read the secret file, since I don't want to hardcode the secret here, the system fails to rebuild with this error:

Error: /etc/prosody/prosody.cfg.lua:93: unfinished string near '"secretgoeshere'

When I go and check that lua file, I see that the closing apostrophe (or quotation mark) goes on a new line for some reason:

turn_external_secret = 'secretgoeshere
'

This does not happen when I hardcode the secret in the configuration file and the service runs fine.

Steps To Reproduce

Steps to reproduce the behavior:

1. Set up Prosody with Coturn
2. Enable the turn_external community module
3. Set in extraConfig the turn secret

Expected behavior

The secret should be printed in the lua config file without the closing apostrophe/quotation mark going on a new line.

FYI, readFile-ing a secret wil put it in the (world-readable) store, so this doesn't sound like the best approach

This rewritten prosody module provide a new option environmentFile, I think that is what you want. You can look at the description to see how to use it.
