manage users of vms

[isabel-amon]

Depends on #99

Beschreibung
As a wimi I need to be able to edit the users of the vms that I have, so I can manage who gets to use it. For this I want to be able to see who is currently a user with sudo-rights and who is a user without sudo-rights.
I want to find an edit button on the page that lets me change the users. When I press the save button I want the rights of the users to change.
When I finish editing, I want the puppet-script of the vm to change accordingly.
