> 0.1 is supposed to be the default bloom_filter_fp_chance for LeveledCompactionStrategy
(and 0.01 for all other strategies).
> However, CFPropDefs#applyToCFMetadata() sets bloom_filter_fp_chance before setting compaction
strategy class, so the default bloom_filter_fp_chance is always 0.01 no matter what the compaction
strategy is.
> The fix is to move cfm#bloomFilterFpChance() call below cfm#compressionParameters().
> The attached patch also kills dead default consistency level-related code.
