8c2b76e45: BREAKING CHANGE

The existing loading of additional config files like app-config.development.yaml using APP_ENV or NODE_ENV has been removed. Instead, the CLI and backend process now accept one or more --config flags to load config files.

Without passing any flags, app-config.yaml and, if it exists, app-config.local.yaml will be loaded. If passing any --config <path> flags, only those files will be loaded, NOT the default app-config.yaml one.

The old behaviour of for example APP_ENV=development can be replicated using the following flags:
```
--config ../../app-config.yaml --config ../../app-config.development.yaml
```
