The `DBreadcrumbItem` and `DBreadcrumbContainer` components
introduced in 1239178f49 have
some limitations, mainly that the container has no awareness of
its items, so nothing that requires positional knowledge can
be used. This is needed to use `aria-current` on the last breadcrumb
item, see https://www.w3.org/WAI/ARIA/apg/patterns/breadcrumb/examples/breadcrumb/.
We change `DBreadcrumbItem` to always be a link, removing
the need for `LinkTo`. Then, we introduce a service to keep
track of containers and items (since all items are rendered into
all containers) and make the item itself responsible for registering
to the service, and introduce the needed `aria-current` behaviour.

This commit introduces the following components:
* DBreadcrumbsContainer - The wrapper template-only component,
which renders all DBreadcrumbsItem components on the page.
* DBreadcrumbsItem - The component that registers a LinkTo
for the breadcrumb trail. The breadcrumb > trail > will
show based on the order these items are rendered on the page.
* BreadcrumbsService - Manages the DBreadcrumbsContainer elements
on the page via DBreadcrumbsContainerModifier.
* DBreadcrumbsContainerModifier - Handles registering DBreadcrumbsContainer
elements with the BreadcrumbsService and deregistering them.
For now, we will only use these breadcrumbs in the admin section
of Discourse, and this initial commit only uses them in admin/plugins.
This is heavily based off of
https://github.com/Bagaar/ember-breadcrumbs,
but will be further modified for our needs.
This commit makes it so the site settings filter controls and
the list of settings input editors themselves can be used elsewhere
in the admin UI outside of /admin/site_settings
This allows us to provide more targeted groups of settings in different
UI areas where it makes sense to provide them, such as on plugin pages.
You could open a single page for a plugin where you can see information
about that plugin, change settings, and configure it with custom UIs
in the one place.
In future we will do this in "config areas" for other parts of the
admin UI.
This commit adds new plugin show routes (`/admin/plugins/:plugin_id`) as we move
towards every plugin having a consistent UI/landing page.
As part of this, we are introducing a consistent way for plugins
to show an inner sidebar in their config page, via a new plugin
API `register_admin_config_nav_routes`
This accepts an array of links with a label/text, and an
ember route. Once this commit is merged we can start the process
of conforming other plugins to follow this pattern, as well
as supporting a single-page version of this for simpler plugins
that don't require an inner sidebar.
