Ability to execute "Manual event actions" on Zabbix Problems panel (#2024)

This PR resolves the below issues:
#2022 #1465 

Specifically, when executing a script on the problems panel, we do check
if the script scope is event or host.
Based on the script scope, the Zabbix API call is constructed
differently.
