Platform: OpenStack IPI
When users want to create a Glance image for RHCOS with `clusterOSImage` option, the installer always sets qcow2 disk format regardless of the local file extension. Sometimes it's required to set `raw` format, if the file extension is `raw`.
What did you expect to happen?
If custom image extension is `raw` (i.e. rhcos-46.82.202010011740-0-openstack.x86_64.raw) the installer should set `raw` disk format instead of qcow2.
