Fuzz knobs to see how they effect performance

FoundationDB has a lot of internal knobs, but there has not been a systematic effort to understand how the effect performance.

The issue names no files, tests, or entry points. Begin by locating FoundationDB’s internal knob definitions and performance measurement entry points, then define a reproducible way to vary knobs and compare results. Done should include systematic findings that explain which knobs affect performance and under what conditions.
