Allow different config.yaml per environment

[philipp94831]

Currently, there is only a global config.yaml. Similar to defaults and pipeline files, it would be good to allow config overrides per environment by creating files such as config_development.yaml for development specific configurations

How should we deal with the environment field in the config.yaml? How would that look in the different environments configs?

I guess it should become a cli param
