Restore default routing patterns and routing groups

[cruzccl]

When a new brand is created, default routing patterns and routing patterns groups are populated with countries and continents. If brand operator deletes them, there is no way to recreate them.

Add a button in each section that allows restoring default routes (and groups) after deleting them.

If we add this button I would avoid creating them during the brand's creation process.

This will speed up A LOT Brand's creation and the administrator could generate the patters if they want by pressing that magic button.
