[Feature][Integration] Opsgenie

[danir-de]

Hi ✌️,

Nagstamon with Nagios/Icinga is a very helpful tool and also allows integrating the new world of clouds, thanks to the Prometheus integration provided in #623.

Having multiple monitoring environments (Nagios, Prometheus, Icinga,...) and the need for tracking and handling SLAs in one place makes Opsgenie a perfect solution for centrally collecting and handling issues.

The only thing missing would be a Nagstamon integration for Opsgenie, so that it's possible to continuing to use Nagstamon to keep everything at a glance while at the desk.

Would it be possible to write a Nagstamon integration/plugin for handling Opsgenie alerts?

Hi @danir-de,
I myself won't find the time to do it but if someone else offers a merge request it is very welcome.
