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:
