[Launch Instance Fix] Fix donut chart title data and standardize design

[Tyr Johanson]

Currently, each step passes in settings for the donut charts. These can be standardized in the chart itself, and overrides removed from each step. In addition we can add constants to the charts for label names (so that they may be translated) and css classes. These can then be leveraged for validation UX. In addition, there is a bug where the chart title shows (# Max), however this # is not really the Max limit and instead is a sum of usage, added and available. We should add a maxLimit property to the chartData object that when passed will ensure it stays intact and therefore can be used for validation. If no maxLimit is specified, the current chart logic can be used to sum the usage, added and available items, but we should change the title to show (# Total) instead of (# Max)

    Fix donut chart title data and standardize design

    This patch updates the chart widget with default styling for donut
    charts and labels. It also updates CSS to more closely match mockups.
    The patch also adds a constant for quotaChartDefaults for label text
    and colors. This patch also fixes a bug where the chart title would
    show more than what was available rather than max. A 'maxLimit'
    property was added to accommodate validity. This patch also adds
    validation UI to warn user when over quota.
