Setting desired_capabilities

[givigier]

I'm running a crawler with the selenium_firefox engine but I got the following exception Selenium::WebDriver::Error::InsecureCertificateError:. As I see on this link https://github.com/SeleniumHQ/selenium/wiki/Ruby-Bindings#ssl-certificates it's something I need to configure on firefox.

Is it possible to set the option desired_capabilities through Kimurai?

@vifreefly Hi, I created this PR #46 just as note about how I fixed the issue. I would like to know how you think is the best way to add this option and of course, to know if makes sense to add this option to the project.

Thank you.
