Dev server HTTPS options are overwritten with --https set

[Addvilz]

When --https is set using command line, https options in dev server configuration are overriden and generated certificate is used instead of the one provided.

If --https is not set using command line but https options are set in dev server configuration, entrypoints.json are generated using http:// prefix instead of https://. Dev server serves all content over https as expected.

I could accept a need to use both config and cli flag, just that having the CLI flag should not overwrite dev server config.

In webpack.config.js

  // ...
  .configureDevServerOptions(config => {
    config.http2 = true;
    config.https = {
      key: '/etc/ssl/server.key',
      cert: '/etc/ssl/server.crt'
    }
  })
 // ...
