Random error when uploading the image to glance

Seen on all versions

OpenStack IPI without `clusterOSImage` in install-config.yaml, so an image is pushed into glance

1. Write an install-config.yaml without `clusterOSImage:`
2. Run the `openshift-install create cluster` command
3. The image upload randomly (not often) fails with the error.
