Add a local to remote option in graphs in ntopng webui

[FedmahnK]

What would you like to add or change?:

In Interfaces Graph, we have a lot options, but it presents data from all sources/destinations. I would like to be able to filter the graph with local <-> remote flow the same way we can filter in live or historial flow view.

The data in influxDB is accessible, I can use it to acheive this view in grafana (with remote2local and local2remote data):

Why do you and others need this?:

Sometimes, we can't easily pinpoint Internet trafic based on interfaces only. Using local network we defined in configuration is pretty useful in my case.

Hi @FedmahnK you were right we missed the visualization of the remote2local and local2remote timeseries, i pushed those two timeseries in a new version, in a couple of hours a new build should be available, update and let me know if it works correctly
