Add header to cli (#2296)

* Add header to cli

Now there is a switch to display the header on user info.
While doing that, I've changed how the command is working to display
all users by default and to accept more than one user at once.
I also changed the display to make it more pleasing.

As this command displays all users by default. I wonder if we still
need the list user command.

See #2294

* Minor format
