Support Automated Private Worker Pool Key Rotation

Description: There is currently no way to automate private worker pool key rotation in Spacelift. The only available mechanism is a manual reset via the console (Manage Organization → Worker Pools → Reset), which immediately disconnects all workers and requires a planned maintenance window.

Request: Provide an API or automated mechanism to rotate private worker pool keys without requiring full worker disconnection, enabling teams to rotate on a regular cadence (e.g. 90 days) without manual intervention or downtime.

Desired outcome:

• API-driven key rotation support

• Graceful worker reconnection (no hard disconnect/maintenance window required)

• Ability to integrate rotation into existing secret management pipelines (e.g. Azure Key Vault)
