Add new counters and statistics for:
a) total read data - since process start, last interval and per fd
b) total write data - since process start, last interval and per fd
c) counts of read IO block size - since process start, last interval and per fd
d) counts of write IO block size - since process start, last interval and per fd
e) counts of all FOP types passing through it
Usage:
1. For dumping global stats
sh# setfattr -n io-stats-dump /tmp/filename /mnt/gluster
2. For enabling per-fd stats
option dump-fd-stats on
