Add unique IDs to stack field notifications to prevent dropping "duplicate" messages

📑 I have found these related issues/pull requests

There are some issues regarding failing monitors. But I did not find issues with webhooks being dropped by the receiving api which may look like a failing monitor.

🔖 Feature description

At least the stackfield notification type seems to not sending a unique id in its webhook. The stackfield API we send this to does not accept recurring messages, so if a monitor goes down and up multiple times the webhook message is being dropped.

✔️ Solution

It would be nice if the webhook could send a hidden unique id in each of its json message. Maybe something like a unix time stamp.
