Current implementation doesn't delete all versions of the record with purging a record

Repro steps:

• create a record with the PUT API
• create another version of the same record with the PUT API
• hard delete (purge) the record

Expected: All metadata and storage blobs should be purged

Actual: Metadata gets purged, but only latest version gets purged. This leaves dangling references of other versions in Blob Storage

Note: The bug was observed for Azure implementation, but other providers should confirm the behavior and put in a fix if required
