Volume chain snapshotting

Hi Mark !

It should be possible to use move disk to do it. (Define same storage
twice, without volume-chain  and another with with-volume chain, and
move to qcow2).

Alternatively, I think it could be possible to simply enable it on your
current storage (in storage.cfg directory), and do the move disk to
qcow2 format.
(but be carefull to not have existing internal snapshots, as it's not
supported to have both kind of snapshots at the same time)
