Use thread_local instead from some static settings (#5955)

Browse source 
thread_local permits to limit variable lifetime to thread duration. Use it on each setting place which uses static to cache variable result only for thread lifetime. This permits to keep the same performance level & reconfigure server from MT gui in those various variables places.

Add thread_local to undersampling calculation too.
