[STORM-1206] Reduce logviewer memory usage through directory stream
Using DirectoryStream to replace File.listFiles will save logviewer memory
usage since it does not require loading all files' metadata into memory. This
avoids potential memory usage problem in extreme case (e.g., you have millions
of small files in your log directory).
Also, a multi-phase PQ-based sorting and cleaning scheme is introduced in
DirectoryCleaner for replacing the global in-memory sorting.
