There is a bug in this PR. Here is the sample output

{
    "valid_vms": [
        {
            "href": "http://localhost:3000/api/transformation_mappings/2222",
            "name": "amaya-at",
            "cluster": "Default",
            "path": "RHV/Default",
            "allocated_size": "32212254720.0",
            "id": "2222",
            "reason": "OK"
        }
    ]
}

"href": "http://localhost:3000/api/transformation_mappings/2222" should be for VM, nottransformation_mappings
