Carousel Controls Hard to Reach for Keyboard Only Users

[greenyouse]

Problem:
The carousel slides currently come before the carousel controls in the DOM.

Impact:
This makes it harder for keyboard-only users to tab to the carousel controls. To get there they need to tab through all of the slide contents first which is more difficult.

Recommended Solution:
Move the carousel controls (.control-dots) above the slides (.slider-wrapper) in the DOM without affecting the current visual styles. Having the controls be slotted first will allow keyboard only users to tab into the carousel controls before getting to the slides.

This part is looking good too with the latest changes on master. I'm going to close this out.
