Title: added group_user_del function to delete a user from a group

added group_user_del function to delete a user from a group

This can be done quickly on RedHat/CentOS with the groupmems command :
sudo("groupmems -d %s -g %s" % (username, groupname))

It does not seem to exist on other distrib (ubuntu) though.
