Hi [~linyiqun], yes. I am trying to split that part of code and get the utility committed,
I see more review comments in HDFS-11779 so it might need more time. Have a simpler patch
to implement a common API, so the other 4 tasks will be able to move on. Otherwise they are
kind of blocked now.

> There are quite some *LIST* operations need to get a range of keys or values from levelDB,
and filter entries with key prefix. 
> # HDFS-11782 listKeys
> # HDFS-11779 listBuckets
> # HDFS-11773 listVolumes
> # HDFS-11679 listContainers
> we need to implement a common utility for them.
