Feature Overview (Goal Summary)

 This feature introduces automatic Etcd snapshot functionality for self-managed hosted control planes, expanding control and flexibility for users. Unlike managed hosted control planes, self-managed environments allow for customized configurations. This feature aims to enable users to leverage any S3-compatible storage for etcd snapshot storage, ensuring high availability and resilience for their OpenShift clusters.

Goals (Expected User Outcomes)

• Primary User Persona: Cluster Service Providers 
• User Benefit: Enhanced data protection and quicker disaster recovery for Hosted Clusters clusters through automated etcd snapshots.

Requirements (Acceptance Criteria)

• Automatic Snapshot Creation: Etcd snapshots must be taken automatically at regular intervals.
• S3 Storage: Support for any S3-compatible storage for snapshot storage.
• Snapshot Rotation and Retention Policy: Snapshots are rotated/removed after a specified period to manage storage efficiently.
• Restoration SOP: Standard Operating Procedures for Etcd restoration should be established, targeting a recovery time objective (RTO) of approximately 1 hour at max. Preferrearbly automated as well. 
• Metrics: Track Mean Time to Recovery (MTTR) for improved reliability. Do we have metrics?
