Quota summary graphs, added styling to indicate percentage full

At 80% the chart becomes orange indicating nearly full
At 100% the chart becomes red just as in the quota bar graphs
when creating new instances, volumes, etc.

Same color scheme across overview charts and progress bars when loading
instances, etc.

Fixes bug where reaching a limit when creating a new instance would
cause the progress bar to have square corners instead of rounded ones

Fixes: bug #1102461
