Use the correct arrows in alias in domain_traffic dashboard

--> should be <-- here instead since the traffic is being received by the FI port from the peer and bytes_rx_delta is used. There are other places in the dashboard files where I have observed this as well.

ucs_traffic_monitor/grafana/dashboards/domain_traffic.json

Line 13264 in c20b991

"alias": "$col $tag_port --> $tag_peer, $tag_peer_slot/$tag_peer_port",

Thanks for finding it. I will scrub the dashboards and make the change.
