Allow launch options as part of Config

[ghost]

I have been unable to find a way with the default Conductor setup to pass launch configurations to the browser with the Configs, like one would normally do with the Options classes.

My proposed solution may look something like:

@Config(browser = Browser.CHROME, url="http://ddavison.io/tests/getting-started-with-selenium.htm", options="--headless")

instead of the current solution of:

 ChromeOptions options = new ChromeOptions();
 options.addArguments("--headless");
 WebDriver driver = new ChromeDriver(options);

(I understand that there are already headless webdrivers, this is just a simple example. There are many other launch options that would be useful)

This would be really great.
