Create notify hook for a custom shell script

[ioqy]

Notify via a custom shell script.

The script will be called with the following parameters:

1. Subject
2. Content
3. Status Code

To set the notification hook:

export CUSTOMSCRIPT_PATH="/usr/local/bin/acme-notification.sh"

acme.sh --set-notify --notify-hook customscript

The custom script can look like this:

#!/usr/bin/env sh

subject="$1"
message="$2"
status="$3"

do-something "$subject ($status): $message"
