Création d'un nouveau domaine et d'un groupe admin du domaine (domain admin)

openstack domain create acme
 
openstack group create --domain acme acme_admins
openstack user create --domain acme --password toor acmeadm
openstack group add user acme_admins acmeadm
 
openstack role add --group acme_admins --domain acme admin
