Subject: [PATCH] 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.
