> This Jira will replace the existing ArrayList with DirectoryDiffList to store directory
diffs for snapshots based on the config value of maxSkipLevels. If the config specified is
set to greater than 0, SnapshotSkipList will be used to store DirectoryDiffs  else ArrayList
will be used. The config value is set to 0 by default.
