Description

FileSizeCountTask counts the number of bins inside each buckets.

Try to build on FileSizeCountTask to count what we need for NSSummary as well.

[6.28] Added an independent Recon task to process namespace summary info per objectID in the attempt to decouple with other task modules.\

[7.7] 

New NSSummary schema:

objectId -> int numOfFiles, long sizeOfFiles, int[] fileDistribution, List<objectId> childDir

where childDir is a list of objectIds for the next-level non-key objects.

Modify the NSSummaryCodec.

Modify NSSummaryTask to write the new field into RocksDB
