Steps to Test

1. Go to https://pr1697-pksvk1y2mlhnkwglqkecukewc9y0oft0.tugboatqa.com/admin/structure/dashboard/experimental_dashboard/preview
2. Edit layout
3. Add a section and confirm there are only four layouts (1 Col, 2 Cols, 3 Cols, 4 Cols) that can be used in Dasboard
4. Add any of them and confirm they look good (there will another ticket to make it looks better, once there's a design)
5. Go to any page in the site (for example /accordions/accordions-secondary)
6. Confirm the same custom layouts can be used and not the default by Drupal
