[Experimental] Adds smoke-and-mirrors addon for perf

[discorick]

Adds the the smoke-and-mirrors ember addon to test improvements to render performance.

Problems:

• Dependency https://github.com/runspired/ember-run-raf has an override for the global clearTimeout, unfortunately that messes with Faye.ENV.clearTimeout . Faye.ENV is actually the app's global scope, and when clearTimeout is called, the overridden version of the method is invoked. This in turn throws an illegal invocation error on the browser. I have the error suppressed for the time being by wiping out the clearTimeout method on Faye.ENV
• Attempting to utilize vertical-collection resulted in @rauhryan is looking into it

I was playing with https://github.com/DockYard/ember-in-viewport as well. Using scrolling columns is going to require quite a bit of sophistication to get card elements hiding/appearing properly. A Naive implementation here: https://ilos.video/pAoLub

Update:

Continuing work on the smoke-and-mirrors library today, was unable to reach a reasonable level of success rendering cards. The closest I was able to get was adding an observer on on the vertical-collection component class itself (monkey patch), along with force rendering every item. This is both a hack, and breaks columns ability to scroll.

@rauhryan I think I am just about ready to call this one a no go, unless you would like to take another stab ?

I'd love to pull out the ember-cli upgrade commits or at least get that done on master. Otherwise, I think this PR can be closed

Hm, I might open up a PR against discorick/card-design-layouts with 92ecf01 to prevent any merge conflicts, does that sound ok ?
