Description

Currently rename folder is to get all the keys, and then rename them one by one. This makes for poor performance.

HDDS-2939 can able to optimize this part, but at present the hdds-2939 is slow and still a long way to go. So we optimized the batch operation based on the current interface. We were able to get better performance with this PR before the hdds-2939 came in.
