Review comment:
       I am still thinking about the best name for this. I did suggest `MetadataLocationUtil` but I am no longer sure it is a good one. Since we will be dealing with files that are reachable, we can consider `ReachableFileUtil` or similar.
   
   Any ideas, @RussellSpitzer @karuppayya @flyrain @kbendick?
