Allow setting browser commandline args via capabilities

[jan-imrich]

When using this driver from behat, there is no way of setting the browser commandline args (ie. --headless or --start-maximized for chrome).

mink-selenium2-driver allows to specify chromeOptions under extra_capabilities (and similar with other browsers). It would be nice if it was compatible, so you could switch between mink-phpwebdriver-extension and mink-selenium2-driver.

I have tried to hardcode
$capabilities['goog:chromeOptions']['args'] = ['--start-maximized'];
into buildDriver() metod and it seems to work, so it should be a matter of just passing those arguments through.

Maybe there already is other way of doing this, but I couldn't figure it out.

In order add "capabilities" you need to access webdriver:

        $desiredCapabilities = $this->getDesiredCapabilities();
        $chromeOptions = $desiredCapabilities->getCapability(\Facebook\WebDriver\Chrome\ChromeOptions::CAPABILITY);

or

        $desiredCapabilities = $this->getWebDriver()->getCapabilities();
        $chromeOptions = $desiredCapabilities->getCapability(\Facebook\WebDriver\Chrome\ChromeOptions::CAPABILITY);

if using Behat, I'd suggest trying https://github.com/oleg-andreyev/MinkPhpWebdriverExtension

but I haven't updated it, because I no longer use Behat myself.
