Description of problem:
Rest API creation of the pool from a template with COW disks fails with "Thin provisioned template disks can not be defined as Raw" while the same pool creation is allowed in UI.
Rest API creation of a new VM from the same template is allowed.

Version-Release number of selected component (if applicable):
ovirt-engine-4.4.6.5-447.gd80dda7.9.el8ev.noarch

How reproducible:100%


Steps to Reproduce:
1. As a base I take a VM created from latest-rhel-guest-image-8.3-infra. 
   Add to the VM virtio_scsi disk, create template from the VM (this additional virtio_scsi disk is added as RAW format).

2. In UI we can create a pool from such a template. 
In rest API though it fails with validation error 'Cannot create VM-Pool. Thin provisioned template disks can not be defined as Raw.'

POST https://{{host}}/ovirt-engine/api/vmpools
<vm_pool>
    <name>pool_from_template_p</name>
    <size>2</size>
    <cluster>
        <name>golden_env_mixed_1</name>

        <ballooning_enabled>true</ballooning_enabled>
    </cluster>
    <template id="{{template_id}}"/>
    <vm/>
</vm_pool>

Actual results: error

Expected results: must be created if it is allowed in UI and if the new VM creation is allowed by rest API .
