    Description

      For HDFS-1073, we need to be able to continue to load images in the old "fsimage/edits/edits.new" layout for the purposes of upgrade. But that code will be only for backwards compatibility, and we want to be able to switch to new code for the new layout. This subtask is to separate out much of that code into an interface which we can implement for both the old and new layouts.
