    Init Glance database only on the node with the database backend
    
    Since [1] Glance init depends on either g-api or g-reg being
    enabled.
    This broke multinode g-api deployments with singlenode database
    backend.
    This commit aligns Glance with other services w.r.t when to
    apply database init.
