Ability for admins to create new user accounts

We are currently hosting a limited access Decidim instance that requires signing in with the organization's internal authentication system before seeing any content. Anyone signs in using their system can access the system as well as users who have user accounts already in the system (i.e. admins) The client has reported a problem that some temporary employees are not always given the credentials to their internal services. Therefore, they would like to manually create user accounts for these people. I suggest it would be possible for system administrators to create new user accounts through the admin panel. A natural place for this would be in the new "Participants" view (Admin -> Participants -> Participants).
