[Bug] OpenStack Compute variable handling of image_id and image_name for Gluster nodes is broken

[HauptJ]

What happened?

Gluster compute nodes cannot be built due to variable mishandling.

If only image_name is set in the cluster.tfvars, the image_id is retrieved, and is set as the image_name for the compute module. This also happens when image_gfs is set with a valid image name. Even if only image_gfs_uuid is set with a valid image_id, the compute image_name is set with the corresponding image_id value.

Since this is blocking my work on #12901 I will work on resolving this first.

What did you expect to happen?

The correct image_id compute module variable is passed through for Gluster compute nodes.

How can we reproduce it (as minimally and precisely as possible)?
