User Management - real management features

Actually, it is not possible to:

• import users from csv (or any other kind of format)

• export the list of users to csv (or any other kind of format)

It would be less important if assigning a task to someone not listed would not fail (see idea CNV-I-556). But, as long as there is a risk of failure, we need ways to monitor who has access and to import people from our domain, or from the SSO-related security group.
