Various improvements are made for collecting congestion statistics:

 - Pre-existing logic is replaced with use of an hrtimer for increased
   reporting accuracy.

 - Congestion timestamp information is reorganized into a single struct.

 - Common statistic collection logic is refactored into a helper routine.
