Enable parallel execution for Selenium

[Crissal1995]

Right now, the execution of Selenium is serial; given N profiles, the tool will run Selenium one by one.
Thus, the more profiles you have in your config, the longer the overall execution will be.

Instead, it looks like enabling Selenium in parallel is possible, as long as N instances of selenium.Chrome() are created for N profiles.

Nice library to check: SeleniumBase. It also handles chromedriver downloads automatically
