Traffic between nodes

[AlexaPal]

Summary

We need to see traffic between any 2 nodes on the links, on the Observability Map.

Desired Behaviour

We would like to be able to create queries that would show traffic attributes (throughput, average response time, etc) between the nodes, to be able to determine at first glance if there is traffic first of all, and if there is any abnormal application behavior.

In case of traffic to databases, we would need to know to which database (database name) the traffic is flowing to (if there are 2 or more JDBC, or MSSQL etc databases)

Additional context

We are transitioning from AppDynamics to New Relic and we have a lot of requests from application teams for a similar Service/Observability Map to the one in AppD. The map is very important to them, for an easier overview of the environment.
