Replace backend packages with Puppeteer.

[dotneet]

I plan to replace some dependent packages with Puppeteer

Here are packages I plan to replace

• chrome-remote-interface
• chrome-launcher

This change would provides less dependencies and more stable behavior backed by Puppeteer.

Hi Shinji @dotneet that sounds like a great idea! If I'm not mistaken Puppeteer is planned to hit v1.0 stable sometime in October. Letting Puppeteer iterate and handle teething issues with browser automation layer while building higher-level features on top of it sounds like great synergy 👍

Hi @dotneet thanks again for Chromy. I was wondering if you have plans to get to this or plans to get others to help out.

I recently compared chromy and puppeteer performance for a simple screenshot tool and noticed that the puppeteer version was considerably faster. I think it would be really nice to see this performance in chromy itself, especially if it gives BackstopJS a performance boost.
