When a user creates a VM snapshot, the only available information on this snapshot is its name.

The actual details about the snapshot are described in the vmsnapshotcontent CR.
We need to expose this information since it is important to be able to identify the actual volumes that are related to the snapshot and their sizes. We need to link to it from the VirtualMachineSnapshots page.

There is a view for the volume snapshot which has "snapshotcontent" column, attached a screenshot.
