Thanks [~jyotindersingh] for working on this. Please create upgrade related

> [FSO] Support upgrade for the bucket layout
> -------------------------------------------
>
> Key: HDDS-6040
> URL: https://issues.apache.org/jira/browse/HDDS-6040
> Project: Apache Ozone
> Issue Type: Task
> Components: OM
> Reporter: Rakesh Radhakrishnan
> Assignee: Jyotinder Singh
> Priority: Major
> Attachments: Bucket Layout Support - Upgrade Framework Onboarding.pdf
>
>
> 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.
