[SUGGESTION] Recovery alert replies the original message

[cesarmagazord]

First of all, thank you for opening this repo and work on this script.

It's possible to reply the first alert message when a trigger is recovered instead post a new message? Something like in the Rocketchat script.

IMO, the conversation is more organized and it is possible to see which alert has not yet been resolved, without having to open the Zabbix panel.

Thank you!
