WIP: Use node-config to read app config
pubsweet-server
no longer has a config.js file, so use node-config
to get the app config.
I think the load-config.js
file can also be removed as it doesn't need to set process.env.NODE_CONFIG_DIR
any more, but I'm not sure so haven't done that here.
There needs to be a new release of pubsweet-server
before this can be tested with updated dependencies.
