Saner API for Logger Summary: The Logger API is quite messy, having multiple functions which differ from one another just by the parameters passed in. This diff consolidates the whole functionality into just 2 functions, which are semantically more meaningful than what we have today - besides representing less code to maintain in the future -.

Cleanup: I/O read/write byte counters Summary: Production data showed that we just have around ~4.5% of traces where the stats are open. The trend is that newer versions have less devices providing io stats. The amount of data is not substantial for any practical use, so I am removing this functionality.

Switch 100% to /profilo subfolder in FileManager Summary: I noticed that my traces are created in `cache/` folder and sometimes both in `cache/` and `cache/profilo` folders. I think we can safely remove migration portion now and switch 100% to `profilo` subfolder. As having this duality seems to be error-prone. Every time a user clears the cache we end up in the migration behavior. Reviewed By: BurntBrunch Differential Revision: D13371068 fbshipit-source-id: cc45c01358f5b3eadb2164f986c119ee7d46e051
