Link some users to a DAR

[ymarcon]

Currently only the applicant has access to the DAR (except DAOs and admins). It should be possible for the applicant to allow read-only access to its DAR to other users. These users should/could be the ones mentioned in the application form.

• Collaborators
  • [x] Collaborators can be added by invitation sent by the applicant (email), until the DAR has not been approved.

  • [x] A collaborator must accept the invite (validates the email address and set permissions to access the DAR)
  • [x] A collaborator can be withdrawn by the applicant at any time. DAR access will be lost.
  • [x] Collaborators are listed in the dashboard page of the DAR, with their respective status (pending / accepted).
  • [x] Collaborators having an account can access the DAR in read-only mode and make comments
• Notifications
  • [x] The invite is a notification email containing the DAR page link.
