Link: https://jira.ez.no/browse/EZP-23704

## Description
Breadcrumbs for the admin pages.

## Tests
Manual test

## TODO
- [x] Apply on all template
- [x] Refactor pjax_admin.html.twig ?

@dpobel I took care of the formating remark except for here where I left indentation. I can change it if you want. I hate horizontal scrolling and I think it makes sense to be able to view all params with a single glimps :)
