Objective

This pull request aims to allow overriding portal default twig templates.
Historically the portal allows to set the templates for the default layout, the home page and for the tiles and pages of brick instances. We project a new look for the portal and needs to replace more templates that the ones allowed.

Proposed solution

Create a new service for managing templates.
Any PHP class can then registry templates by implementing an interface TemplatesProviderInterface.

AbstractBrick and AsbtractController implements this interface, so any brick or controller can provides his own templates without implementing interface.

Datamodel module_design properties accept any templates handled by the service

New Symfony profiler view for the template service:
