Add a progress bar component

[GuessWhoSamFoo]

There is currently no component that shows a task running to completion. We should support showing indeterminate and determinate progress.

A progress bar should be a stand alone component but also support embedding in cards, summaries, etc.

I guess Deliverable:

• storybook story.
• An angular component
• Go component with config to control the state of the component.

Do we have to add anything for the JS plugins?
