Using multicast for image transfer

In huge environments network is bottleneck during simultaneous node provisioning. By starting group deployment over multicast will minimize network utilization. And will minimize resource utilization on image storing servers.

Baremetal nodes that are spawned with the same user image may be grouped. Since user image is equal on all nodes there is no need to send it by unicast directly to each node. Rather ironic should wait until all nodes in the group are ready to receive user image. Once it is done "user image" should be transfered to all nodes simultaneously via multicast.
