```
I'm going to update with those fixes, and then actually move to a leaner
version of this PR
* no rework of stats context/interfaces
* just make S3AInstrumentation classes all serve up IOStatistics, with
common base classes
This will massively reduce the s3a code diff, and meets the core goal of
"easier for apps to pick up statistics of application use".
