Removed fsyncExceed from stats command, but the tracking variable still
remains in ServerStats. I was thinking of moving it to for example zkDb, but
that wouldn't make any more sense in my opinion.
The other option is to leave it in FileTxnLog as a static variable, that
was my original idea actually.
So if that is a better solution, I will change it.---
