block: New option to define the intervals for collecting I/O statistics
The BlockAcctStats structure contains a list of BlockAcctTimedStats.
Each one of these collects statistics about the minimum, maximum and
average latencies of all I/O operations in a certain interval of time.
This patch adds a new "stats-intervals" option that allows defining
these intervals.
