Fix the parent collections for hardwares/disks

VMware has the vms_and_templates inventory collection not vms +
miq_templates so we need to update the hardware and disks accordingly
otherwise we get the error:

```
[RuntimeError]: Can't find InventoryCollection vms from InventoryCollection:<Disk>
```
