Why not ['--headless', ...(options.chromeFlags||[])] ?

what when someone does not want --headless mode, then it's not possible to override flags? Anyway I am open to that change because I will never want to run chrome without headless flag :)

Hm.. We cannot force the use of --headless. We can set it as a default as @gorangajic has done, but a user needs to be able to omit it. There are valid use cases where you'd want to see what's happening in a window. Another approach would be to add a headless: true parameter to the constructor options which defaults to true, then add the headless flag based on that. In some ways I prefer this as its more explicit and the behavior is clearer (rather than, if you want to disable the headless flag, knowing to pass an empty array of chromeFlags.) @joelgriffith what do you think?

We could go the route of passing in a hash of options:
{ headless: true } => '--headless'
{ remoteDebuggingPort: 1234 } => '--remote-debugging-port=1234'
{ headless: false, disableGpu: true } => '--disable-gpu'
This way you can splat new params into place, and still have defaults like headless

remoteDebuggingPort is already behind cdp options and chrome is using port provided there so no need to duplicate that logic here. Whatever you guys want, I am open to changes

I also like the object hash option
