Our donut charts do not look like they should in Patternfly. https://www.patternfly.org/patterns/donut-chart/ uses c3, so we can do that too.
Eventually I want to remove flot_pies too, but I have to yet figure out how to auto refresh donut charts.
Adding this library also will allow us to change our charts in Host#show to the newer style. https://www.patternfly.org/widgets/#basic-charts
