Description

Add Request Validators for the prefinalization state during the upgrade for Bucket Layout feature.

OMBucketCreateRequest when asked to create an FSO bucket can lead to the persistence of new metadata that will not be compatible with an older version of the OzoneManager in case of a downgrade.

The behavior in such a case is defined as follows:

• Only LEGACY buckets can be created in the pre-finalized state.
• Requests to create FSO/OBS buckets will be denied in the PRE_PROCESS phase itself.
