Feature http headers (#276)

Implement feature flag to pass headers to Puppeteer via "headers" option.

Also, add feature flag to set headless mode via "headless" option.

Update headless behavior to sync with puppeteer API change. See: https://developer.chrome.com/articles/new-headless/#new-headless-in-puppeteer
