Add Example for Rotation Windows

Rotation windows

Summary

This MR adds a new example to the documentation showcasing how to implement rotation windows using the time_rotating resource.

Usage scenario

An organization is managing access to sensitive systems using time-limited tokens for security reasons. The tokens are used to authenticate with an external API (e.g., Grafana, AWS, or another cloud service). To maintain security:

• Tokens must be rotated frequently to reduce the risk of compromise.
• There should be no downtime during token rotation to ensure uninterrupted service.

Challenges without overlapping rotation windows

• Service Downtime: If a token expires before a new one becomes available, dependent systems will face authentication failures.
• Race Conditions: During token rotation, a lack of coordination can cause systems to use an expired token while waiting for the new one.
• Operational Complexity: Manual or poorly timed token updates require more monitoring and introduce potential errors.
