Update Card LESS to PatternFly core

Part of #676

Base Card Aggregate Status Card Trends Card Utilization Card Info Status Card

I'd recommend taking a screenshot of card as it is now in a-pf, and a screenshot of how it is in PF.org and/or test pages. Also get the LESS/CSS used in both repos side by side to compare. Where possible move/remove LESS from a-pf repo. The goal is to have as little as possible LESS in a-pf and use LESS/CSS which is in PF Core. Make changes in angular-patternfly, possibly more LESS into PF core. When done take another screenshot of changes and compare to original screenshots.
