Steps to Reproduce:
1. create VM with http / attach cloned disk source
2. delete the VM and uncheck Delete Disks
3. create the same VM (you can change things like http source) with the same name again
the VM returns an error: Failed to create DataVolume: admission webhook "datavolume-validate.cdi.kubevirt.io" denied the request: Destination PVC already exists
The VM gets and DVs get created and can start sucessfully
We should generateName for all of our dataVolumes (also for example in clone-modal, etc.)
