Add breadcrumbs to module pages

Pivotal [#62544642].

This PR makes breadcrumbs configurable on a view basis, and then adds them to all pages so that they are of the form:

- Dashboard: "Performance"
- Module: "Performance > Parent dashboard"

This provides a bit of navigation from our page-per-thing pages back to our dashboards, and differentiates page-per-things of the same type a bit.
