[pve-devel] [PATCH v3 container 1/2] api: clone_vm: don't include snapshot properties

apparently this caused a weird[0] bug... when a container with a snapshot was
cloned, it would take 'parent: foo' from the original container. if you
add a new snapshot 'bar', and then another one 'foo', this causes the
snapshots to become parents of each other (thus not parsed correctly in
the tree view of GUI nor with 'pct listsnapshot CTID')

we also drop these properties for VMs, so it makes sense to do the same
here as well.
