    libvirt: Allow use of live snapshots with RBD snapshot/clone
    
    The recently merged functionality for making use of RBD snapshot/clone
    when available is very valuable for the Ceph/RBD users out there.
    The new method also makes it possible to do live instance snapshots
    with Ceph/RBD.  However, the current code explicitly forbids it.
    
    This patch allows the use of live instance snapshots when a RBD
    snapshot/clone is performed directly, and reverts back to cold
    instance snapshot when the old method is used.

  However, it is also possible to enable live_snapshots when this
  feature is used.

  I have a proposed patch that allows to enable this.
