GSoC Refactor: CLI Refactor (CLI/API Uniformity Improvements, webpack-cli serve)

[knagaitsev]

I decided to separate this from the clientMode/serverMode refactor effort. Here are my plans:

• make any "CLI Only" options available to API as well (e.g. devServer.progress)
• bring options handling in bin/webpack-dev-server to a bare minimum
• minimize createConfig such that it only normalizes CLI arguments to API options, but does not handle defaults. Instead, the API should handle setting defaults.
• move the logic of bin/webpack-dev-server into webpack-cli serve, such that webpack-cli serve calls the Dev Server API.

Issue created at webpack-cli: webpack/webpack-cli#900

EDIT:

• make the CLI throw an error (or possibly just a warning for backwards compatability?) if an argument is provided that does not exist
