Subject: [PATCH] Only start one glance_api when using file backend
The default backend storage for Glance in Kolla is file, as this is the
easiest to deploy. However, this leads to frustration in a multinode
scenario as the volumes aren't shared.
This change sets glance_api to only start on one control node when using
the file backend.
