Add funcional test to check cant start vm during restore
Add funcional test to check cant start vm during restore

The test creates a vm and snapshot offline.
Then using a dummy webhook which fails creating
the PVC for the restore - stucks the restore
in progress. Then we make sure that changing the
vm to running fails and only after the deleting the
webhook and making sure the restore is complete
we can start the vm.
