[pve-devel] [PATCH guest-common 2/4] replication: prepare: return additional information about snapshots

[Fabian Ebner <f.ebner@proxmox.com>]

This is backwards compatible, because existing users of prepare() only
rely on the elements to evaluate to true or be defined.

Signed-off-by: Fabian Ebner <f.ebner@proxmox.com>

Depends on pve-storage for the new volume_snapshot_info function.

Build-breaks old pve-manager, because the test there assumes
volume_snapshot_list is used.
