As a site owner, I want editors and customers to have different profiles.

Summary

• Add a built-in Customer for visitors (customers) interacting from the frontend
• Simplify the current User content type so that it is suited for backoffice users (editors, etc)
• Change the default configuration to use the Customer content type for frontend registration
• Enhance the user_registration configuration so that the user content type can be set per siteaccess

User content type (backoffice)

• first name
• last name
• user account
• picture
