The initial bundling has to finish before closing the process

• Operating System: macOS 10.13.3
• Node Version: 9.2.1
• NPM Version: 5.8.0
• webpack Version: 4.2.0
• webpack-dev-server Version: 3.1.1

• This is a bug

Expected Behavior

When I precss Ctrl+C during the initial bundling I expected the process to abort.

Actual Behavior

When running webpack-dev-server through CLI, I have to wait for the initial webpack bundle to be built before I can close the process. This is not necessary for webpack-cli, so is this restriction required for webpack-dev-server?

For Bugs; How can we reproduce the behavior?

Run webpack-dev-server CLI and immediately press Ctrl+C.

For Features; What is the motivation and/or use-case for the feature?

Initial bundling can take a long time, so if you realize you made a mistake in the configuration or you're iterating through different configuration combinations, you always have to wait until the initial bundle is finished.
