Nagios integration - Events sent to wrong Nagios server

Issue Summary

Upon checking the Opsgenie Nagios documentation it looks like we have  the ability to send action back to the source Nagios server when there are multiple servers
https://support.atlassian.com/opsgenie/docs/integrate-opsgenie-with-nagios-plugin/#Opsgenie-Plugin-Configuration-in-Nagios

The python script bundled with the Nagios package does not have the logic to handle the parameter (Nagios_server) to send the action back to the Nagios server.

Steps to Reproduce

Tried setting up a Nagios instance in my lab but unfortunately was unable to set up a full-fledged Nagios environment to replicate this particular scenario

Expected Results

The script is not sending the action back to the appropriate Nagios server 

Actual Results

The below exception is thrown in the xxxxxxx.log file:

Workaround

Currently, there is no known workaround for this behaviour. A workaround will be added here when available
