unable to configure Onlyoffice documentserver default.json file

[hatch01]

Describe the bug

I am unable to edit the /run/onlyoffice/config/default.json file to configure onlyoffice documentserver through nix parameters. And if I edit it manually, it is overwritten on each reboot.

Steps To Reproduce

Steps to reproduce the behavior:

1. enable onlyoffice document server services.onlyoffice = {enable = true; hostname = "localhost";};
2. echo /run/onlyoffice/config/default.json
3. reboot
4. the modification in default.json disappear

Expected behavior

Being able to configure the default.json file directly in the service config. It is a json file, so maybe it is possible to just set any parameters from the nix config to the json file with a simple conversion from nix to json.

Additional context

In my case, I need to modify these values :

      "request-filtering-agent": {
        "allowPrivateIPAddress": true,
        "allowMetaIPAddress": false
      },

I tried to add this which according to this line

  environment.sessionVariables = {
    ALLOW_META_IP_ADDRESS = "true";
    ALLOW_PRIVATE_IP_ADDRESS = "true";
  };

But this does not seem to have any effect.

We are doing some hacky stuff at https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/web-apps/onlyoffice.nix#L220-L259

we probably need to add a new option, to generally patch that file.
