Should be aware of control flow deprecation

[manoj9788]

Just raising this, work on changing parts where control flow is used. If you guys are already aware and have plans to change we can close this.

Thanks @manoj9788....Selenium 3.0.0 is on my radar, but I hadn't actually spent much time looking at the new async stuff yet. We'll leave this issue open to make sure it's on our minds as we move forward.

@hoverduck Sure, am happy to help. I will soon put a new repository on the new async showcasing a demo.

We probably need to prioritize this now that we're on Node 8.9.x

We should move to using async/wait: https://github.com/SeleniumHQ/selenium/wiki/WebDriverJs
