With this change, MinIO's ILM supports transitioning objects to a remote tier. This change includes support for Azure Blob Storage, AWS S3 compatible object storage incl. MinIO and Google Cloud Storage as remote tier storage backends. Some new additions include: - Admin APIs remote tier configuration management - Simple journal to track remote objects to be 'collected' This is used by object API handlers which 'mutate' object versions by overwriting/replacing content (Put/CopyObject) or removing the version itself (e.g DeleteObjectVersion). - Rework of previous ILM transition to fit the new model In the new model, a storage class (a.k.a remote tier) is defined by the 'remote' object storage type (one of s3, azure, GCS), bucket name and a prefix. * Fixed bugs, review comments, and more unit-tests - Leverage inline small object feature - Migrate legacy objects to the latest object format before transitioning - Fix restore to particular version if specified - Extend SharedDataDirCount to handle transitioned and restored objects - Restore-object should accept version-id for version-suspended bucket (#12091) - Check if remote tier creds have sufficient permissions - Bonus minor fixes to existing error messages Co-authored-by: Poorna Krishnamoorthy <poorna@minio.io> Co-authored-by: Krishna Srinivas <krishna@minio.io> Signed-off-by: Harshavardhana <harsha@minio.io>
