* ui: Loader amends/improvements
1. Create a JS compatible template only 'glimmer' component so we can
use it with or without glimmer.
2. Add a set of `rose` colors.
3. Animate the brand loader to keep it centered when the side
navigation appears.
4. Tweak the color of Consul::Loader to use a 'rose' color.
5. Move everything loader related to the `app/components/` folder and
add docs.

This PR removes storybook and adds docfy and uses docfy to render our existing README files.
This now means we can keep adding README documentation without committing any specific format or framework. If we eventually move to storybook then fine, or if we just want to remove docfy for whatever reason then fine - we will still have a full set of README files viewable via GitHub.
