MinIO alternatives for unsupported Bucket resources

For calls to BucketACL or ObjectACL operations, use Policies.
Calls to BucketCORS operations are not needed because CORS is enabled by default on all buckets for all HTTP verbs.
For calls to BucketWebsite operations, use caddy or nginx.
For calls to BucketAnalytics, BucketMetrics, or BucketLogging operations, use Bucket Notifications.
