Expiring non-versioned objects fails

Note: Only buckets with versioning enabled can be configured for replication.

To expire non-versioned objects correctly, we currently rely on the InvalidBucketState error returned when the S3C Backbeat API is used for a non-versioned bucket's object, until CLDSRV-461 is implemented to add support for non-versioned buckets to the Backbeat API.

Issue : BB-555
