debug/io-stats: Adding stat for weighted & unweighted average latency
Summary: - Our current approach to measuring "average fop latency" is badly flawed in that it doesn't weight the FOPs correctly according to how many occurred in the time interval. This makes Statisticians very sad. This patch adds an internally computed weighted average latency which will be far more efficient to display via ODS, as well as having the benefit of not being complete nonsense.
