[pve-devel] New Backup Strategy - pve-manager patch

[Jeff Moskow]

This patch (and the associated pve-common patch) provide for new backup functionality.

  1.  Allows idle machines to be skipped if they have already been backed up
  2.  Allows multiple storages to be assigned to a backup job and for vzdump to pick the best place to store a backup

The only known limitation is that if a VM is stopped and then migrated and not restarted on the new node, it will appear unchanged.
