node_firmware_update_status – gets sent on node firmware update progress/status changed 
				
					{
    event = "node_firmware_update_status",
    node_id = 2,
    target = 0,
    status = "finished",
    progress = 100
}
node_firmware_update_status must be sent for each target separately and for all node firmwares with nil target. Possible order of statuses: 
				
					{ event = "node_firmware_update_status", node_id = 42, status = "started" }

{ event = "node_firmware_update_status", node_id = 42, status = "started", target = 0 }
{ event = "node_firmware_update_status", node_id = 42, status = "in_progress", progress = 50, target = 0 }
{ event = "node_firmware_update_status", node_id = 42, status = "finished", target = 0 }

{ event = "node_firmware_update_status", node_id = 42, status = "started", target = 1 }
{ event = "node_firmware_update_status", node_id = 42, status = "in_progress", progress = 50, target = 1 }
{ event = "node_firmware_update_status", node_id = 42, status = "finished", target = 1 }

{ event = "node_firmware_update_status", node_id = 42, status = "finished" }
