feature

What is the current behavior?

According to my understanding and tests, I can use webpack either in combination with a config file which includes the entry and output paths, or I can pass the entry and output path as CLI arguments. But both alternatives are mutually exclusive, i.e. I cannot overwrite the entry and output paths specified in a config file through CLI parameters, while still using the other specifications in the config file.

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

I want to use a webpack.config.js AND overwrite the entry and output paths of that config file using CLI parameters.

If this is a feature request, what is motivation or use case for changing the behavior?

I need to change entry and output paths dynamically and depending on some context while keeping the other entries of an entry file.

Please mention other relevant information such as the browser version, Node.js version, webpack version and Operating System.
