> Currently we check if an index file on the master and slave is the same by checking if it's name and file length match.
> With LUCENE-2446 we now have a checksums for each index file in the segment. We should leverage this to verify if two files are the same.
> Places like SnapPuller.isIndexStale and SnapPuller.downloadIndexFiles should check against the checksum also.
