Description

When first loading from an empty log, there is a case where MetadataLoader can publish an image before the bootstrap records are processed. This isn't exactly incorrect, since all components implicitly start from the empty image state, but it might be unexpected for some MetadataPublishers. 

 

For example, in KRaftMigrationDriver, if an old MetadataVersion is encountered, the driver transitions to the INACTIVE state.
