[Feat]: Agent Connectivity Topology Map

[ss-mbrancato]

Problem

I am not sure in some cases if a node is streaming to a parent or direct to netdata cloud easily.

Description

I would like to see some sort of topology map for my netdata agents to let me know at its most basic level which agents are directly connecting to the cloud and which ones are connected to a parent and which one.

Importance

nice to have

Value proposition

1. This would help troubleshoot connectivity and ensure that configuration files are working as expected.
2. This would also let us view potential blast radius of bringing a given parent down.

Proposed implementation

leverage the existing data widget for parent, child, standalone and the network connection top function to build a network diagram
