block: Compute minimum, maximum and average I/O latencies
This patch keeps track of the minimum, maximum and average latencies
of I/O operations during a certain interval of time.
The values are exposed in the BlockDeviceTimedStats structure.
An option to define the intervals to collect these statistics will be
added in a separate patch.
