LibreNMS support

[ciroiriarte]

Hello, will you be willing to accept a PR including LibreNMS as an alternative to Cacti for KPI tracking?.

Hi, I don't mind having another system for tracking KPIs. I don't have hands-on experience with LibreNMS so I'm not 100% on this. I suggest to provide a very early draft for us to see what you intend to do. Or a description of how you see the interaction between both systems.

The same comment about upstream vs. downstream applies like in issue #7 .
