This patch adds cluster support to these methods:
- update_consistencygroup
- update_group
- create_cgsnapshot
- create_group_snapshot
- create_snapshot
- copy_volume_to_image
- accept_transfer
- get_backup_device
- secure_file_operations_enabled
- get_manageable_volumes
- get_manageable_snapshots
APIImpact: Now listings of manageable volumes and snapshots accept
cluster parameter.
