> 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.
