issue: ENG-6618
We want to warn the dev that they are not using identity credentials for communictaing with the clients
For now using identity credentials is optional. The dev can proceed with their setup. If they want to start using the identity credentials though, they need to restart nix and go through setting up a new keyserver.
If the keyserver is run in Docker, the dev should set usingIdentityCredentials flag in COMM_JSONCONFIG_secrets_user_credentials env variable and create a new keyserver. See doc
We don't need this warning on the prod keyserver - it will not have the flag set, but that's fine, because the dafualt 256 is its id.
