Use a local image instead of a shared storage image
Description
This hook add the ability to use fast local storage instead of shared
storage, while using shared storage for managing VM templates.
To enable this hook, the VM should have a custom property of 'localdisk=lvm'.
The system administrator will be responsible for creating the host "ovirt-local"
volume group and extending it with new devices if needed.
The VM must be pinned to host.
