> [HADOOP-13065] added a new interface for retrieving FS and FC Statistics. This jira is to track the effort of moving the {{Statistics}} class out of {{FileSystem}}, and make it use that new interface.
> We should keep the thread local implementation. Benefits are:
> # they could be used in both {{FileContext}} and {{FileSystem}}
> # unified stats data structure
> # shorter source code
> Please note this will be an backwards-incompatible change.
