OCPBUGS-17161 - hide footer after a few seconds

[aireilly]

https://issues.redhat.com/browse/OCPBUGS-17161

The footer is currently obscuring content at the end of the page. The previous convoluted js solution to adjust the page is broken. Maybe some recent Chrome or HTML/CSS spec change.

This is a pretty dumb solution, no css fades etc but it works :shrug:
