Description

Steps to reproduce:

1. cd compose/upgrade && docker-compose up -d (if it fails, fix the permission of the dirs, and repeat the up command)

2. create /vol1/bucket1/dir1/dir2/key1

3. list the keys in /vol1/bucket1

4. stop the cluster

5. modify the docker-config by enabling prefix layout:

OZONE-SITE.XML_ozone.om.enable.filesystem.paths=true
OZONE-SITE.XML_ozone.om.metadata.layout=prefix

6. start the cluster

Expected behavior: Fail to start OM as the configured cluster layout and persisted bucket layout mismatches. Presently, there is no validation during OM startup.
