Rake tasks to assign permissions to users
Created by: seif
Added 2 rake tasks to add users to all projects in the system.
One to import all users to all projects with system admins as masters, and the other just assigns adds a user as a develop to all projects.
Needed this for a new installation of gitlab with a lot of imported projects. users logged in using ldap and then just run the task to assign permissions. might be useful to some1 else.
