Need to discuss this change once, we do not support UDS for FNS Blob

Description of PR:
This PR is in correlation to the series of work done under Parent Jira: [HADOOP-19179]
Jira for this Patch: [HADOOP-19233]
Currently, we only support rename and delete operations on the DFS endpoint. The reason for not supporting rename and delete operations on the Blob endpoint is that the Blob endpoint does not account for hierarchy. We need to ensure that the HDFS contracts are maintained when performing rename and delete operations. Renaming or deleting a directory over the Blob endpoint requires the client to handle the orchestration and rename or delete all the blobs within the specified directory.
The task outlines the considerations for implementing rename and delete operations for the FNS-blob endpoint to ensure compatibility with HDFS contracts.
