Description

This task is to discuss and implement upgrade finalization. Also, should support downgrades from pre-finalized state of OM.

Overall Upgrade logic could be like,

OM should not allow to create FSO/OBS layouts before finalization.

Implement ClientBucketLayoutValidator - In Pre-finalization, if client sends explicit bucket layouts (FSO and OBS) to OM server then OM will give a warn message and create the bucket with LEGACY layout.
