    [FLINK-1968] [runtime] Clean up and improve the distributed cache.

     - Gives a proper exception when a non-cached file is accessed
     - Forwards I/O exceptions that happen during file transfer, rather than only returning
null when transfer failed
     - Consistently keeps reference counts and copies only when needed
     - Properly removes all files when shutdown
     - Uses a shutdown hook to remove files when process is killed
