Description
In follow up to CASSANDRA-5371. We now perform size-tiered file selection for compaction if L0 gets too far behind, however as far as I can tell we stick with the CF configured false positive ratio, likely inflating substantially the number of files we visit on average until L0 is cleaned up. Having a a different bf fp for L0 would solve this problem without introducing any significant burden when L0 is not overloaded.
