Disable warning about configuration file not found

[sergejostir]

We can now set all configuration options with env vars without using our own config file (ebb18fa). However, on every startup a warning is logged saying that the configuration file could not be found.

I guess there should be an option added to specify that sftpgo shouldn't go looking for a configuration file?

Hi,

I think we don't need a new configuration option for this, please take a look here thank you!
