feat(random-alerts): Add initial package and module

[MartinNikov]

Service Overview: Randomized Alert Loop

This service operates in an infinite loop, triggering alerts at randomized intervals within a defined range.

• Timing:

  • Minimum wait time: 1 hour (default)
  • Maximum wait time: 4 hours (default)
  • After the minimum wait, a random time within the remaining window is chosen for the next alert.

• Alert Behavior:

  • Alerts are triggered via curl to a specified Alertmanager URL.
  • Alerts last for a configurable duration (default: 1 hour).
  • Alerts auto-resolve after the duration ends.

• Logging Options:

  • info: Logs when an alert is sent and its success status.
  • debug: Also logs the scheduled time for the next alert.

🚨 Default Configuration: 6 Alerts per 24 Hours 🚨

I dislike the regularity of the random alerts. As they are right now, they are very predictable as there are certain invariants in place. There are gaps that are guaranteed to not have alerts in them. Could you explain the purpose and reasoning behind this design?
