User registration

• New users can register into the system using a registration link. These links are generated by the system administrators using the user email address. These email address will be the user identifier in the system
• On the registration page, the user should introduce the following data:
  • email address (the same one used for generating the registration link)
  • tenant Id
  • User role (creator or follower). This selection will determine if the user is registered as a PaaS user (activity creator) or as a SaaS user (follower)
